Welcome to gdcsim!

During my annual leave over the festive season I started hacking on this (YA) logic circuit simulator.  I still need to force my employer to sign a copyright disclaimer; that is why I have not yet imported any sources.  I have no reason to believe that Prism will refuse to disclaim all copyright interest - I have emails from two fairly big wheels and neither had a problem with releasing non-competing software as Free Software.

Early successes I can report:

I believe the core of the simulation engine is okay; I had no trouble setting up an example circuit of switch - inverter - probe and watching a switch flip propagate to the probe.

Next new feature I'd like to see:

gdcsim should be able to read circuit description files.  Currently circuits are described by code which is then compiled.  I haven't decided on the primary file format yet, but I'd like to see an XML-based format.  Suggestions most welcome.  Above all, gdcsim should support file format modules, so that integration with, say, gEDA is possible.

I would like to be able to estimate the level of interest in my first SourceForge project; please email me (berndj@prism.co.za) if this looks like an interesting project to you.  I'll send respondents a note as soon as the source becomes available.

That's it for now!
