There is a new development snapshot available ... http://gnucap.org/devel/gnucap-2008-03-24.tar.gz
Models (optional) have also been updated, fixing some attachment problems: http://gnucap.org/devel/gnucap-2008-03-24-models-bsim.tar.gz http://gnucap.org/devel/gnucap-2008-03-24-models-ngspice17.tar.gz http://gnucap.org/devel/gnucap-2008-03-24-models-spice3f5.tar.gz Another optional package contains some tools. There are no changes, but there is a new one for consistency. http://gnucap.org/devel/gnucap-2008-03-24-tools.tar.gz This snapshot provides mostly clean-up and bug fixes. There is one new feature. It now accepts parameters on ".subckt" lines, with Spice syntax. The old ".param" syntax still works. Some bug fixes: Temperature mapping with multiple devices with spice-model plugins. "sin" frequency default is now the same as Spice. Bring back "get", "merge", "build" (in the last snapshot, they only worked with dots.) Comments: This is still very much a development snapshot, and should not be included in any distribution or CD. Performance with spice model plugins is very slow. The copy-in-copy-out mapping does have some speed penalty, but the speed is much slower than it should be. Also, convergence is not what it should be, which slows it down more. As it stands, the spice model plugins do not support any of the "fast-spice" ability that gnucap has. Fixing this is high priority, before a stable release, but after a feature freeze. Plugins using the spice-wrapper still do not take named parameters, or expressions. As usual, to get started you need only the main package gnucap-2008-xx-xx.tar.gz . The other "models" packages contain the exact models from the various sources. If you need a jfet, I recommend the one in "spice3f5". If you need a BSIM model, the obvious choice is the "bsim" package, which has all of them. The "ngspice17" package contains a few models not available elsewhere, such as "vbic". If you need other models, let me know. Others, such as Josephson junction, are available, but I have not ported them yet. Porting a Spice model usually requires two files, a "Makefile" and a "wrapper.h", and no other changes. _______________________________________________ geda-dev mailing list [email protected] http://www.seul.org/cgi-bin/mailman/listinfo/geda-dev
