This is a great step forward to make simulation within the geda context a viable alternative to the less stubborn. A simulation suite desperately needs a set of generic models of standard parts. Else, potential users will turn elsewhere before they become users. Of course, there are more essential ingredients to actually attract a substantial user base. Next on the list is a workflow that is at least as smooth and reliable like gschem->pcb->gerber. And of course, a complete set of tutorial, examples, manual and in depth documentation. Are there plans to achieve these essentials with gnucap, or ngspice? Is an active developer working on it? Is there a road map? ---<)kaimartin(>--- -- Kai-Martin Knaak tel: +49-511-762-2895 Universität Hannover, Inst. für Quantenoptik fax: +49-511-762-2211 Welfengarten 1, 30167 Hannover http://www.iqo.uni-hannover.de GPG key: http://pgp.mit.edu:11371/pks/lookup?search=Knaak+kmk&op=get _______________________________________________ geda-user mailing list [email protected] http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
