Simulation using Gnucap

In this example Hec is used as a front-end to Gnucap. Gnucap and Gnuplot are run by perlscripts.

You can run these perlscripts by clicking SuperL-Alt-button1 on 'simcon'-symbol. Simulation plots are presented according to configuration data embedded in the 'simcon'-symbol.

You can change the 'simcon' text using an editor of your choice by clicking Shift-Alt-button1 on the 'simcon'-symbol.

Fig 2. The content of the 'simcon'-symbol opened in Emacs (server mode). To open emacs click on the 'simcon'. (e.g. Shift-Alt-button1 on simcon)

Gnuplot graphs

When another 'simcon'-symbol, simcon_AC, is clicked upon (e.g. SuperL-Alt-button1) the corresponding simulation graph pops up.

In this simcon there is another setup text controlling how the simulation is to be done, and how data should be presented.

Annotation of Gnucap results into schematics

Gnucap results, like DC-levels, can be read back and presented in the Hec schematic. A nice little feature that makes it easy to set resistor values.

One goal for Hec is to test features like this to get some idea whether they are useful or not.

You can try all these example yourself, and much more. Run Linux. Install Emacs, Perl, Gnucap och Gnuplot. And Hec, of course.
