Installed Files

The Qucs system needs several programs. These are installed during the installation process. The path of Qucs is determined during the installation (configure script). The following explanations assume the default path (/usr/local/).

  • /usr/local/bin/qucs - the GUI
  • /usr/local/bin/qucsator - the simulator (console application)
  • /usr/local/bin/qucsedit - a simple text editor
  • /usr/local/bin/qucshelp - a small program displaying the help system
  • /usr/local/bin/qucstrans - a program for calculation transmission line parameters
  • /usr/local/bin/qucsfilter - a program synthesizing filter circuits
  • /usr/local/bin/qucsconv - a file format converter (console application)

All programs are stand-alone applications and can be started independently. The main program (GUI)

  • calls qucsator when performing a simulation,
  • calls qucsedit when showing text files,
  • calls qucshelp when showing the help system,
  • calls qucstrans when calling this program from menu “Tools”,
  • calls qucsfilter when calling this program from menu “Tools”,
  • calls qucsconv when placing the SPICE component and when performing a simulation with the SPICE component.

Furthermore, the following directories are created during installation:

  • /usr/local/share/qucs/bitmaps - contains all bitmaps (icons etc.)
  • /usr/local/share/qucs/docs - contains HTML documents for the help system
  • /usr/local/share/qucs/lang - contains the translation files

Command line arguments

qucs [file1 [file2 ...]]

qucsator [-b] -i netlist -o dataset (b = progress bar)

qucsedit [-r] [file] (r = read-only)

qucshelp (no arguments)
