It is windoze-style, fully integrated, complete with the baggage. I find it confusing to use, but I don't do windows. On the plus side, it does a good job at RF. It has harmonic balance, which no other free simulator has. On the minus side, The time stepping transient analysis is primitive. Model support is poor, in the sense that anything needs to be ported. It uses a wierd netlist format that is only compatible with itself. There are lots of "models" included, in the sense of the Spice ".model" cards. Just comments .... There is a lot of cookbook code, straight out of numerical analysis texts. I'm not sure how much of it is actually used, as opposed to just being there. There are a lot of other tools, such as filter synthesis, included in the package, accessable by menu. I prefer the old unix style, with lots of small tools, each doing one job well. With some help, gEDA and gnucap could be better in all areas. What we lack is in integration and in the easy but tedious parts. I get the impression that they have a large team, with more "junior" people than we have, as you would find in some academic environments. If we could combine the resources of gnucap, ngspice, and qucs, we would have more than some of the big spice projects, probably more than LTspice, and could easily come out on top. Too bad it seems it will never happen. _______________________________________________ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
