Gnucap is not designed as a drop-in replacement of Spice. That would be a waste of time. Rather, it is designed as a followup to Spice, bringing free simulation up to date, and hopefully taking the lead. In commercial simulators, there are lots of them that are just Spice. In that regard, NGspice is our spice. Then there are those that move beyond, in many ways. They sell for a much higher price than any Spice. This is the "mixed signal", "fast spice" and lots of others. The only reason they haven't completely replaced Spice is MARKETING. They can sell a Spice cheap, and make big bucks on the new one. Gnucap is designed with full knowledge of Spice and others, to address the big shortcomings of Spice, and move on. I am referring to the real issues here, not the ones that can be easily fixed. Unfortunately, progress has been hampered by a development team that is far too small, and not much open community involvement. _______________________________________________ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
