DLD V 2.0 Released Digital Logic Design is a Software tool for designing and simulating digital circuits. It provides digital parts ranging from simple gates to Arithmetic Logic Unit. You may start your circuit from simple gates and flipflops and keep on converting them into ICs. These ICs, later on, may be incorporated into other circuits to built more complex circuits like CPU. You may even use SOP expressions to generate digital circuits in IC form. You can use this software to design Combinational, Synchronous and Asynchronous Sequential Circuits. The circuit working can be analyzed by using output parts like LEDs, Seven Segment Display as well as CRT and digital Oscilloscope all provided in the software. This Software may be used by professionals, hobbyists and students alike. The teachers may incorporate this software in their courses like Digital Logic and Computer Design, Computer Architecture, Computer Organization and Embedded Systems.

GridLAB-D is a new power system simulation tool that provides valuable information to users who design and operate electric power transmission and distribution systems, and to utilities that wish to take advantage of the latest smart grid technology. It incorporates advanced modeling techniques with high-performance algorithms to deliver the latest in end-use load modeling technology integrated with three-phase unbalanced power flow, and retail market systems. Historically, the inability to effectively model and evaluate smart grid technologies has been a barrier to adoption; GridLAB-D is designed to address this problem. User documentation can be found at: http://gridlab-d.shoutwiki.com/wiki/Quick_links The source code is available from GitHub. See https://github.com/gridlab-d/gridlab-d. Issue tracking is handled by GitHub. See https://github.com/gridlab-d/gridlab-d/issues.

gVirtualXRay is a C++ library to simulate X-ray imaging. It is based on the Beer-Lambert law to compute the absorption of light (i.e. photons) by 3D objects (here polygon meshes). It is implemented on the graphics processing unit (GPU) using the OpenGL Shading Language (GLSL). SimpleGVXR is a smaller library build on the top of gVirtualXRay. It provides wrappers to Python, R, Ruby, Tcl, C#, Java, and GNU Octave.

JMCAD is an program for the modeling and simulation of complex dynamic systems. This includes the ability to construct and simulate block diagrams. The visual block diagram interface offers a simple method for constructing, modifying and maintaining complex system models. The simulation engine provides fast and accurate solutions for linear, nonlinear, continuous time, discrete time, time varying and hybrid system designs. With JMCAD, users can quickly develop software or "virtual" prototypes of systems or processes to demonstrate their behavior prior to building physical prototypes. The user builds his system model by selecting predefined blocks from a block library and simply wiring the blocks together. Each block of the diagram performs a function. Users can also create custom blocks in Java and add them to the JMCAD block library. JMCAD is a block diagram language for creating complex nonlinear dynamic systems.
