Fizzim is a finite state machine design tool for building readable FSM diagrams and generating Verilog/SystemVerilog.

Fizzim 2.0 extends the original Fizzim workflow with forked transitions, state groups, transition actions, linting, modern canvas editing, and a public regression flow that compares Fizzim 2.0 feature diagrams against generated Fizzim 1.0-compatible diagrams.

The app uses a simplified Fizzim 2.0 splash screen with an integrated F² wordmark and matching F² icon.
