There is a new development snapshot available ... http://gnucap.org/devel/gnucap-2008-12-03.tar.gz
Optional plugin files: There are some changes, so get these too: http://gnucap.org/devel/gnucap-2008-12-03-models-bsim.tar.gz http://gnucap.org/devel/gnucap-2008-12-03-models-jspice3-2.5.tar.gz http://gnucap.org/devel/gnucap-2008-12-03-models-ngspice17.tar.gz http://gnucap.org/devel/gnucap-2008-12-03-models-spice3f5.tar.gz http://gnucap.org/devel/gnucap-2008-12-03-tools.tar.gz This file contains the md5sum of the other files, so you can check for a proper download: http://gnucap.org/devel/gnucap-2008-12-03.md5sum This snapshot provides no real new features, just bug fixes and general cleanup. The 2008-10-10 snapshot was very buggy. Among the improvements: 1. Two bugs in the native MOS1,2,3,6 models regarding threshold voltage calculation and temperature effects have been fixed. I think the bugs were introduced with the model compiler, but I am not sure about that. The bugs only showed with certain combinations of options, so regression tests missed them. For years, I blamed small differences on something else. Now, they have good correlation, in all tests including high frequency AC, with the Spice models. Compared to the Spice models (as plugins) the native models are probably faster and have more data available through probes. 2. There has been some serious cleanup of the file "spice-wrapper.cc" which is used as an interface to all Spice C model plugins. All spice model plugins benefit from this. 3. As a deviation from the policy of making absolutely no changes to externally supplied models, some Spice models have a bug that results in incorrect parameters being used for AC analysis after a transient analysis. The models that needed a fix include all bjt and diode models (including bjt2 and vbic) in the spice3f5 and ngspice17 tarballs. The models in the jspice3-2.5 tarball did not have the bug. === As usual, to get started you need only the main package gnucap-2008-xx-xx.tar.gz . If you need other models or functions, let me know. _______________________________________________ geda-dev mailing list geda-dev@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-dev
