Qfsm - Tool for designing finite state machines

Friday, 23 January 2009 22:39

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:

Drawing, Editing and Printing of states diagrams;
• Binary, ASCII and "free text" condition codes;
Integrity check;
Interactive simulation;
Diagram export in the formats: EPS, SVG and PNG;
AHDL/VHDL/Verilog HDL/KISS/vvvv Automata code export;
State table export in Latex, HTML or plain text format;
Ragel file export (used for C/C++, Java or Ruby code generation)
State Chart XML (SCXML) export

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.
