Requirements

You will need the following programs to be installed.

1. A recent version of gEDA/gaf. To see if your version is recent enough, see if the directory $prefix/share/gEDA/sym/switcap exists. $prefix is the installation prefix for gEDA on your system.

2. SWITCAP. The executable is usually called sw. If you do not have SWITCAP available on your system, you will need to contact Columbia University to obtain a copy. The gEDA/gaf SWITCAP support was tested with SWITCAP Version A.5R Release 21-Sep-87.

3. Although it is optional, you may wish to install a tool which can be used for plotting the output data. SWITCAP produces both ASCII data listings as well as ugly ASCII plots (note the release date of the version of SWITCAP used). Suitable tools are:
   • Gwave. Gwave is an analog waveform viewer. It is fairly basic, but easy to use, includes cursors, and has zoom/pan features. See http://www.geda.seul.org
   • Scilab. Similar to matlab. Powerful, but no cursors or panning. See http://www-rocq.inria.fr/scilab
   • Octave. Similar to matlab. See http://www.octave.org
   • Grace. See http://plasma-gate.weizmann.ac.il/Grace/
