QElectrotech is a Qt4 application to design electrotechnical diagrams, domestic and industrial electrical schemas. Diagrams (*.qet extension) and electric elements (*.elmt extension) are stored using the XML format files. QElectrotech includes both a diagram editor and an element editor.

           

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.

             

XCircuit is a UNIX/X11 program (realeased since 3.6.0 version with Artistic License) for drawing publishable-quality electrical circuit schematic diagrams and related figures, and produce circuit netlists through schematic capture. XCircuit regards circuits as inherently hierarchical, and writes both hierarchical PostScript output and hierarchical SPICE netlists. Circuit components are saved in and retrieved from libraries which are fully editable. XCircuit does not separate artistic expression from circuit drawing; it maintains flexiblity in style without compromising the power of schematic capture. There are drawing programs, and there are schematic capture programs. All schematic capture programs will produce output for inclusion in publications. However, these programs have different goals, and it shows. Rarely is the output of a schematic capture program really suitable for publication; often it is not even readable, or cannot be scaled. Engineers who really want to have a useful schematic drawing of a circuit usually redraw the circuit in a general drawing program, which can be both tedious and prone to introducing new errors. XCircuit is flexible enough to be used as a generic program for drawing just about anything, and is competitive with powerful programs such as xfig. It is especially good for any task requiring repeated use of a standard set of graphical objects, including architectural drawing, printed circuit board layouts, and music typography.
