QucsDigi — A wrapper script for digital simulations.


qucsdigi [OPTION] infile outfile time dir bindir vlibs


Qucs is an integrated circuit simulator which means you are able to setup a circuit with a graphical user interface (GUI) and simulate the large-signal, small-signal and noise behaviour of the circuit. After that simulation has finished you can view the simulation results on a presentation page or window.

The software aims to support all kinds of circuit simulation types, e.g. DC, AC, S-parameter, harmonic balance analysis, noise analysis, etc.

QucsDigi is a wrapper script for digital simulations performed by Qucs. The program utilizes the FreeHDL compiler in order to convert the VHDL output of Qucs into a C++ program. Thereafter this C++ source is compiled and linked to a binary. This binary is then executed and its VCD output file is converted to a Qucs dataset.


the filename of the VHDL file to be simulated located in the directory specified in DIR
the filename of the Qucs dataset file to be produced
duration of the digital simulation
the name of the directory where the simulation is going to be performed
the location where the qucsconv program is installed
a -Wl linker option passing extraneous libraries against which resulting simulation binary is linked


The latest version of Qucs can always be obtained from www.sourceforge.net or www.freshmeat.net
