enable loop counter (VCL)

enable loop counter (VCL)

Title: ENABLE TRUE COUNTED HOMINGLOOPS

The enable loop counter function is used at or near the beginning of the Declaration
section of a test to enable true counted homingloops. The function operates in conjunction
with the times parameter in the homingloop function.
• Without enable loop counter, the times is used only by the SAFEGARD safety analysis
routines. If the loop fails to exit, it runs until test timeout occurs.
• With enable loop counter, if the loop fails to exit after it has run the number of times
specified by the times parameter, the test fails.
The enable has no effect on homingloops that do not use the times parameter.

Syntax
enable loop counter

Parameters
(none)

Examples
! in the Declaration section of the test
enable loop counter

enter (BT-Basic)

enter (BT-Basic)

Title: ENTER DATA

The enter function enables sequential input of data from files or devices, using free- field
format. For imaged formatting of the data, refer to the enter using function.
The input device or file is specified in the function's <data source> parameter. A device is
assumed to be a part of the file system. The file or device can be addressed either by its
<file id> or by an @<name> associated with that <file id> by an assign to function. If
<file id> is used, the file or device opens for the access and then closes when the access
is completed. If an @<name> is used, the file or device is opened when the @<name> is first
assigned, and the file or device then remains open for sequential access; that is, each new
access to the file or device starts where the previous access stopped.
The input data are assigned, in the order in which they are input, to the variables listed in
the function. The input data must correspond, item for item, to the types—numeric or
string—of the listed variables. The data items being input must be separated from each other
by a delimiter, as described below.
The enter function accesses data sequentially, starting at the first record and reading the
data record by record. As the data is read, the system tracks its current read position by
moving a pointer through the data. Assuming that the file was not closed, the next access to
the data then starts at the current position of the pointer—that is, at the beginning of the
next record. If you wish to skip the pointer over one record, you can do so by omitting the
variable list from the enter function. To return the pointer to the beginning of the first
record, close the file or device and then reopen it.
The rules applying to the input data are listed next. They are the same as the rules listed
for the input function, except that input must have at least one item in its variable list.

Numerical Input
1 Numbers must contain only valid characters, in the proper order.
2 The delimiter between numbers can be a comma, a space, or a RETURN (EOL or EOR).
Extra spaces before or after the delimiter are ignored.
3 A null input can be made to any one numeric variable—i.e., the variable retains its
current value—by omitting the number and inputting just a comma (with or without
spaces).
4 When all input variables are satisfied, any remaining input, up to the next EOR, is read
and discarded. The input then terminates.
5 A blank line (a null record) also terminates the input. Any remaining input variables
retain their current values.
6 Input data can cross record boundaries, but an individual item cannot.

E-40 Syntax Reference

 enter (BT-Basic)

String Input
1 The RETURN (EOL or EOR) is a delimiter between strings. After the input, the input
variable is the same length as the string assigned to it (the dimensioned length of the
string cannot be exceeded—see the next step).
2 If an input string is longer than the dimensioned length of the variable to which it is
assigned, the extra characters are assigned to the next variable, if there is one.
3 When all input variables are satisfied, any remaining input, up to the next EOR, is read
and discarded. The input then terminates.
4 A blank line (a null record) also terminates the input. Any remaining input variables
retain their current contents.
5 Input data can cross record boundaries, but an individual item cannot.

• When both strings and numbers are to be input, the rules listed above apply. During the
input, if a number follows a string on the same line, then the string must be the same
length as the dimensioned length of the string variable to which it is assigned.

Syntax
enter <data source>
enter <data source>;<variable list>
enter <data source>,,<error variable>
enter <data source>,,<error variable>;<variable list>
<data source> can be: <name>
<file id>
<name> is a <label>
<file id> is a <string expression>
<error variable> is a <numeric variable>
[Note the double comma preceding <error variable>]
<variable list> can be: <variable>
<variable>,<variable>
<variable>,<variable>, . . . <variable>
<variable> can be numeric or string
[Use <array id>(*) to specify a complete array]

Parameters
<data source> The source of the data to be input, which can be either a file or
device. If a <file id> is specified, the file or device is opened to
read the data and then closed, regardless of whether or not the
input operation was successful. If an @<name> is specified, the file
or device remains open for further access. If used, the @<name>
must have previously been assigned.
<error variable> The identifier of an error variable.
<variable list> A list of the names of the variables to which the input data are to
be assigned. Any type of variable, including substrings, can appear
in the list. If a complete array is specified, each element is treated
like a separate input variable.
If the list is omitted, one record of data is read and discarded.

enter using (BT-Basic)

Title: ENTER IMAGED DATA

The enter using function enables sequential input of data from files and devices, using
imaged format. For free- field formatting of the data, refer to the enter function.
The input device or file is specified in the function's <data source> parameter. A device is
assumed to be a part of the file system. The file or device can be addressed either by its
<file id> or by an @<name> associated with that <file id> by an assign to function. If
<file id> is used, the file or device opens for the access and then closes when the access
is completed. If an @<name> is used, the file or device is opened when the @<name> is first
assigned and remains open so that each access to the file or device can start where the
previous access stopped.
The specifications which format and interpret the input data are referenced by means of the
function's <image data> parameter. This parameter can itself contain the formatting
specifications, or it can reference an image function which contains the specifications. The
variable list contains the identifiers of the variables where the input data are to be stored.
The input data are assigned, in order, to the variables listed in the function. The input data,
as formatted by the image specifications, must correspond, item for item, to the
types—numeric or string—of the listed variables, and there must be sufficient data to fill all
of the listed variables.
The enter using function accesses data sequentially, starting at the first record. Only one
record is read, unless the image <line spec> (/) is used to enable record boundaries to be
crossed. If all of the listed variables have been filled before the end of the current record
has been reached, then the data continues to be read until an EOR (End Of Record) is read.
However, this data is discarded. If the input is from an GPIB device, and the inhibit- EOL
spec (#) is included in the image specifications, reading terminates as soon as all the listed
variables are filled.
As the data is read, the system tracks its current read position by moving a pointer through
the data. Assuming that the file or device was not closed, the next access to that data starts
at the current position of the pointer; that is, at the beginning of the next record. If you
wish to skip the pointer over one or more records, you can do so by omitting the variable
list from the enter using function. One record is skipped, unless the image specification
<line spec> (/) is used to skip more than one record. To return the pointer to the
beginning of the first record, close the file or device and then reopen it.
The input data must comply with the following rules, any violation of which causes an
execution error:
1 Each item of data must be the same type (numeric or string) as the variable to which it
is to be assigned.
2 Numbers must contain only valid characters, in the proper order.

Syntax Reference E-43

enter using (BT-Basic)

3 An input string cannot be longer than the dimensioned length of the variable to which it
is assigned. After the input, the actual length of the variable is the same as the length of
the string assigned to it. (The standard rules for assigning a string to a substring apply.)
4 Delimiters (commas, etc.) in the input are ignored. The image specifications determine the
start and end of each data item.
5 Input data can cross record boundaries, but an individual item cannot.
6 Sufficient data must be input to fill the variables in the variable list. After that, data
continues to be read until an EOL (End Of Line) is encountered, unless a suppress EOL
(#) is contained in the image specifications.

<data source> The source of the data to be input, which can be either a file or a
device. If a <file id> is specified, the file or device is opened to
access the data and then closed, regardless of whether or not the
input operation was successful. If an @<name> is specified, the file
or device remains open for further access. If used, the @<name>
must have previously been assigned.

to be used to format the input data.
<image specifications> The list of specifications to be used to format the input data.
Refer to the image function for a complete description of the
specifications.
<error variable> The identifier of an error variable.
<variable list> A list of the names of the variables to which the input data are to
be assigned. Any type of variable, including substrings, can appear
in the list. If a complete array is specified, sufficient data must be
supplied to fill all elements in that array.

If the variable list is omitted, the read pointer advances one or

more records, as determined by the image specifications. The data
skipped during the advance is ignored.

 events every (VCL)

events every (VCL)

Title: SET THE PERIOD OF THE REFERENCE CLOCK

The events every function is used in the Timing section of a VCL test to specify the period
of the testhead reference clock, and to declare the resource which is to synchronize the
reference clock. This function must be the first function in the Timing section, because all
other timing in the test is controlled by the reference clock.
The reference clock is derived from a frequency synthesizer with a phase- lock loop. It can
be synchronized either to the test system's internal clock, or to an external clock; the
external clock can be derived from the board under test, or from any other external source,
routed through the fixture. The synchronizing source is selected by the events every
function:
• internal uses the frequency synthesizer phase locked to the internal clock.
• pll (phase locked) uses the frequency synthesizer phase locked to an external clock.
If pll is specified, the external clock source node must be specified in an outputs
reference clock function, in the Declaration section of the test.

Syntax
events every <event spacing> internal
events every <event spacing> pll <clock time> period edge <polarity>
<event spacing> and <clock time> are <numeric constants>
<polarity> can be: rising
falling

Parameters
<event spacing> The time between events (i.e., the period of the reference clock) in
seconds. The range is:
50 ns (20 MHz) <= event spacing <= 6.25 us (160 kHz)
<clock time> The period, in seconds, of the external clock. The two clock
periods can be equal, or they can be multiples, or sub- multiples,
of powers of 2. The range of the external clock is:
25 ns (40 MHz) <= clock time <= 6.25 us (160 kHz)
<polarity> Specifies the external clock edge to which the reference clock, and
the events, are to be synchronized.

Syntax Reference E-51

events every (VCL)

Examples
! Timing section of VCL test #1

Title: CHANGE THE PERIOD OF THE REFERENCE CLOCK

(Mux systems only)
The events every internal function temporarily changes the period of the reference clock,
which controls test timing by establishing the spacing between events in the timing sets (see
Advanced Testing With VCL in Digital Testing).
The events every internal function in debug is similar to the events every function in
VCL, except that the debug function cannot be used if the test timing is synchronized to an
external clock, or uses vector cycle and receive delay timing.

Syntax
events every <event spacing> internal
<event spacing> is a <numeric expression>

Parameters
<event spacing> The time between events (i.e., the period of the reference clock) in
seconds. See your system's specifications for the range of event
spacing.

execute (BT-Basic)

execute (BT-Basic)

Title: EXECUTE COMMANDS OUTSIDE OF BT-Basic

The execute function is used to execute commands outside of BT- Basic (or executable
programs) from within a BT- Basic window. This function can be used in either of two ways:
1 Executing this function without parameters on the command line changes the current
window into a shell window in which commands outside of BT- Basic can be executed.
This assumes that nowindow is the default in your .hp3070 environment file; if the default
is window, a new shell window opens.When you are finished with the shell window, enter
exit to restore the BT- Basic window.
2 Executing this function on the command line and specifying a command outside of
BT- Basic causes the specified command to execute (subject to the options listed below).

Syntax
execute
execute <command>
execute, <error variable>
execute <command>, <error variable>
execute <option list>
execute, <error variable>;<option list>
execute <command>;<option list>
execute <command>, <error variable>;<option list>
execute <command>; append
execute <command>; append, <option list>
execute <command>, <error variable>; append, <option list>

<command> is a string expression

<error variable> is a <numeric variable>
<option list> can be one or more of the following, separated by commas:
<window>
<wait>
<window> can be:
window
nowindow
<wait> can be:
wait
nowait
failwait

Parameters
<command> A string expression that identifies a valid command outside of
BT- Basic or an executable program.
<error variable> The identifier of an error variable.
<option list> A list of optional parameters that determine how the function
works. How these parameters work is also affected by how their
defaults are defined in the .hp3070 environment file associated
with each login. The options are:
<window> – Specifies whether or not a new window is
automatically opened when the command is executed. Values are:

E-54 Syntax Reference

 execute (BT-Basic)

• window – A new window is opened.

• nowindow – Suppresses the opening of a new window.
<wait> – Specifies how the command executes. Values are:
• failwait – The command executes and, if a failure occurs, the
results remain on the screen so you can examine them.
• nowait – The command executes and does not pause for you to
examine the results.
• wait – The command executes and the results remain on the
screen so you can examine them.
append A keyword that causes the output from a command outside of
BT- Basic or program to be appended to the work area of the
BT- Basic window from which the execute function was invoked.
NOTE: When using append, the only permissible values for <option
list> are nowindow and nowait.

Examples
! Invoke a shell window in which commands outside of BT-Basic can be executed
execute
! Execute a command outside of BT-Basic in a new window
! and immediately return to BT-Basic
execute "rm my_file"; window
! Execute a command outside of BT-Basic in the current window
! and pause only if the command fails; includes an error variable
execute "rmdir test", Error; failwait
! Execute a command outside of BT-Basic in the current window
! and pause to display the results

Title: EXECUTE A VECTOR

The execute function is used in a digital unit, or in a digital subroutine, to execute a single
vector. (Vectors with counters must be executed by the preset counter or count
statements.)
In addition to identifying the vector to be executed, the function can optionally include some
combination of secondary keywords, as shown in the syntax format below. Refer also to the
separate descriptions of the compress, exit if pass and sync statements for more details.

Table E-2 Secondary Keywords for execute

Keyword Description
arm Arm the time interval counter (i.e., frequency, pulse width, and time interval) on the
ASRU card to start timing. The setup must first be made in the analog portion of a
mixed test.
capture Add the states of the capture pins to the capture RAM.
compress Add the received response (from all pins that are not off) to the CRC; cannot be used
in a controller loop, homing loop or unit disable test.
drive Drives pin states from the specified variable.
drive data Drives the current set of pin states from the specified data block.
exit if pass Exit a homing loop when the device is in the required state (i.e., the received outputs
match the expected response in the current vector).
piped Specifies the piped vectors in homing loops (see The Pipe in Digital Testing).
receive Receives the pin states defined in the specified variable.
receive data Receives the pin states defined by the current setting in the specified data block.
sync Generate the sync pulse which appears at a BNC connector on the side of the
testhead.
trigger acv Trigger the AC voltmeter on the ASRU card. The setup must first be made in the analog
portion of a mixed test.
trigger arb Trigger the ARBitrary waveform generator. This function is the same as trigger
source but can be used more than once between continue analog
statements—but, see General Information on page E-60.
trigger dcv Trigger the DC voltmeter on the ASRU card. The setup must first be made in the analog
portion of a mixed test.
trigger detector Same as trigger dcv.

Table E-2 Secondary Keywords for execute (continued)

Keyword Description
trigger digitizer Trigger the digitizer. This function is the same as trigger acv but can be used more
than once between continue analog statements—but, see General Information
on page E-60.
trigger external Trigger the external port set up in the analog portion of a mixed test.
trigger source Trigger the source (i.e., sine, triangle, and square wave) on the ASRU card. The setup
must first be made in the analog portion of a mixed test.
wait Causes the test to wait for a trigger on the wait lines before resuming.

Because of the purpose of each option, only certain combinations can be used. Allowable
combinations of options are:
1 These options can be used alone or with any other options:
• drive
• drive data
• receive
• receive data
• sync
• wait
2 These options can be used alone or with options in 1:
• exit if pass
• piped
3 These options can be used alone, or with options in 1, or with any combination allowed
in 4:
• capture
• compress
4 These options can be used only in mixed tests; they can also be used with options in 1
and 3. Each one can be used only once after each return from the analog test to the
digital test. They can be used alone or in any combination of the following:
• arm
• trigger acv or trigger arb or trigger dcv or trigger detector
• trigger external
• trigger source or trigger digitizer (cannot be used with trigger acv or trigger arb)

with a counter cannot be executed by the execute function: use
preset counter or count.
If the compress secondary keyword is used, then all outputs to be
compressed must be on (i.e., set to 1 or 0 when the vector is
executed); outputs not to be compressed, must be set to X (off).
<variable> The simple variable or array element that contains the pattern of
bits to be driven to, or received from, a group of pins.
<data block id> The data block that contains the pattern of bits to be driven to, or
received from, a group of pins.

General Information
Multiple trigger arb and trigger digitizer options can be specified without executing a
continue analog function between them. However, make certain that there is at least one
active vector executed between the trigger options, to reset the trigger drivers on the ASRU
card—a trigger cannot be initiated if its driver has not been reset. Consider the following
example:
execute V1 trigger arb
wait 20m
execute V1 trigger arb
A wait consists of some number of no- op vectors that execute keeps on all drivers,
including the trigger drivers on the ASRU card. Therefore, because the trigger drivers have
not been reset, the second trigger does not occur. To avoid the problem, place at least one
vector that is not a no- op vector either before or after the wait. If you do not, the compiler
issues a warning.

 exit test (ANALOG)

exit test (ANALOG)

Title: EXIT AN ANALOG TEST BLOCK

The exit test function is used within an analog test block to quit the test block and return
to the testplan. After exiting an analog test block, testplan execution continues at the
function following the test (BT- Basic) function that executed that analog test block. exit
test (ANALOG) is functionally similar to BT- Basic's subexit function.

The exit test function is most useful within an on failure loop. The on failure loop can
be part of an analog test block.
It is similar to BT- Basic's if-then loop. For example, when a test block contains more than
one measurement, such as for a potentiometer, you could stop the test if the first
measurement fails. This would avoid the unnecessary second measurement.
The exit test function opens all relays including GP relays. This is important to note
because relays are not normally opened at the end of analog tests.

Syntax
exit test

exor (BT-Basic)

exor (BT-Basic)

Title: EXCLUSIVE-OR
The exor operator is used to evaluate Boolean expressions. It returns a value of 1 if either
the expression on the left or the expression on the right, but not both, is true (non- zero). If
both expressions are true, or if both are false (zero), the operator returns a value of zero.
This operator has a priority of 1.

Syntax
<numeric expression> exor <numeric expression>

Parameters
<numeric expression> The quantities to be evaluated.

Examples
print 12 exor -123.4 ! prints 0
print 0 exor 345 ! prints 1
print 0*20 exor 0 ! prints 0
A = 25 \ print A exor 0 ! prints 1

exp (BT-Basic)

Title: EXPONENTIAL
The exp function returns the constant naperian e (2.71828182846) raised to the power of the
function's argument.

Syntax
exp(<numeric expression>)

Parameters
<numeric expression> The argument of the function:
argument <= 709.78

Examples
print exp(1) ! prints 2.71828182846

expand homingloop at (DEBUG)

expand homingloop at (DEBUG)

Title: INCLUDE ALL HOMINGLOOP VECTORS ON THE DISPLAY

The expand homingloop at function displays all homingloop machine vectors including the
piped vectors for each pass through the homingloop.
Without this function digital debug displays only the first pass through the loop. See The
Pipe in Digital Testing for an explanation of homingloops and piped vectors.

Syntax
expand homingloop at <vector>
<vector> is a <numeric expression>

Parameters
<vector> The vector number of the last piped vector in a homingloop. This
cannot be a user- specified vector (i.e., a vector containing the
piped keyword).

Examples
expand homingloop at 35

General Information
To determine the number of the last piped vector, look at the header on the display which
indicates the machine vector numbers. The piped vectors are indicated with the letter p and
not a number. The machine vector number of the last piped vector is easily calculated from
the header.
Once a homingloop has been expanded, the information in the header (including machine
vector numbers, user vector numbers and VCL source line numbers) are not correct for the
vectors following the expanded homingloop. If a test contains several homingloops, expand
only one homingloop at a time. Do not attempt to modify, add or delete any vectors
following an expanded homingloop.

 external devices (CONFIGURATION)

external devices (CONFIGURATION)

Title: CONFIGURE EXTERNAL DEVICE CONNECTIONS ON UTILITY CARD

The external devices statement declares external device connections on the optional
Utility Card.
Note the following:
• All external devices slots in a module must be declared (for example, either declare xd1
to xd3 or declare xd1, xd2, xd3 for module 3).
• The device name must be unique across the board.
• One device name must refer to one physical device.
• A device name may be mapped to up to three device slots in a module.
• Device names and their corresponding device slots must be the same in the system and
board config files.
• A device may span multiple slots.
• To use more than one external device simultaneously, a device group must be defined. See
the syntax description for the group statement.
• When using external devices with a panelized board, the external device must be assigned
to a board number. See the syntax description for the board... uses statement.

Syntax
external devices <xd_range> on card <card_id>
<xd_range> can be: <xd_id>, <xd_id>, <xd_id>
<xd_id> to <xd_id>
<xd_id> is xd<integer>
<card_id> is an <integer>

Parameters
<xd_id> The identifier for the external device connection (xd1 to xd12; see
Table E- 3).
<card_id> The identifier for the Utility Card.

 extract version (BT-Basic)

extract version (BT-Basic)

Title: COPY VERSION OF board AND board_xy FILE

When using multiple board versions, extract version allows you to make a separate board
directory for a version of a board. You may want to do this either to keep the version
separate or to create a new base board. This command creates new board and board_xy files
called board.ver and board_xy.ver that include information for the specified version only.

Syntax
extract version ! Extracts the base board to local.

extract version " " ! Extracts the base board to local.

extract version <version label>

! Extracts the specified version from local to local.

extract version <version label> from <board file id>, <board_xy file id>
! Extracts the specified version from elsewhere to local.

extract version <version label> from <board file id>, <board_xy file id> to/over
<board file id>, <board_xy file id>
! Extracts specified version from anywhere to anywhere.

Parameters
<version label> The name of the version to extract.
<board file id> When this parameter follows "from", it specifies the location of the
version of the board file to extract; when it follows "to/over", it
specifies the name of the target board.ver file.
<board_xy file id> When this parameter follows "from", it specifies the location of the
version of the board_xy file to extract; when it follows "to/over", it
specifies the name of the target board_xy.ver file.

Examples
extract version "version_3"

extract version "version_3" from "ABC/board", "ABC/board_xy"

extract version "version_3" from "ABC/board", "ABC/board_xy" to

"DEF/board.ver", "DEF/board_xy.ver"
