There is a new development snapshot of gnucap available. There's a package at: http://www.gnucap.org/devel/gnucap-2007-02-21.tar.gz http://geda.seul.org/dist/gnucap-2007-02-21.tar.gz
This snapshot improves the plug-in support, adds the ability to have commands as plug-ins, and makes almost all of the commands, devices, and models plug-in ready. The Spice wrapper is working, but packaged separately. There are 3 new tarballs available, contaning models: http://www.gnucap.org/devel/gnucap-2007-02-21-bsim-models.tar.gz http://www.gnucap.org/devel/gnucap-2007-02-21-ngspice17-models.tar.gz http://www.gnucap.org/devel/gnucap-2007-02-21-spice3f5-models.tar.gz or ... http://geda.seul.org/dist/gnucap-2007-02-21-bsim-models.tar.gz http://geda.seul.org/dist/gnucap-2007-02-21-ngspice17-models.tar.gz http://geda.seul.org/dist/gnucap-2007-02-21-spice3f5-models.tar.gz These model packages are licensed by a Berkeley license, not GPL. See the COPYING file in each package for details. Since they are ports of the work of others, they determine the license. They must be distributed separately because of licensing. The first one "bsim-models" contains the Spice BSIM3, BSIM4, and BSIMSOI models, as plug-ins. It is a complete set, including the archival versions and the latest. The new BSIM460, released by Berkeley in December, is included. There are 28 models here. The second one "ngspice17-models" contains the complete set of models from ngspice17, as plug-ins. Not all of them work, due to missing support functions in gnucap, but all are included. As a reminder, this is a development snapshot. The semiconductor models do work. The transmission lines probably do not work. The simple devices like resistors and sources only work if they use a ".model". The ones having a plain value do not work. For these, you are better off with the gnucap native devices anyway. The third one "spice3f5-models" contains the complete set of models from spice 3f5, as obtained from Berkeley. Not all of them work. The same points as the ngspice models apply here, for the same reasons. All of these Spice models are supplied without any modifications other than a "Makefile" and a configuration file "wrapper.h". The build and install procedure for the simulator is the same as the previous snapshot. It still has the same link order issue. Work on Verilog-AMS is going well. This is part of it. The simulator core will support only the structural subset, which lets you make netlists. Full behavioral modeling with be supported using a compiler, similar to the existing "gnucap-modelgen". Eventually, you will be able to do "attach my-model.vams", and it will automatically take care of the details to make the .so file and attach it. In the future, a working c and c++ compiler, and make will be required to fully run gnucap. As usual, I am asking for feedback, particularly on non-Linux and non-GNU systems. _______________________________________________ geda-user mailing list [email protected] http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
