Qfsm is a graphical tool for designing finite state machine; Finite state machines are models to describe complex objects or systems in terms of the states they may be in. In practice they can be used to create regular expressions, scanners or other program code as well as for integrated circuit design. Current features of Qfsm are:

Qfsm can export HDL in the file formats; AHDL, VHDL, Verilog HDL, KISS. HDL (aka Hardware Description Languages) are high level descriptions that can be synthesized into integrated circuits like FPGAs using special software. For more information about Qfsm, click here.
