Hello, I have made some important changes to ngspice which fix legal issues as well as architecture compile issues. This release : ngspice_15-4 appears to be frozen ... however un-freezing it will remove some RC bugs. thanks Matt -- http://www.flatmax.org MFFM Bit Stream : http://sourceforge.net/projects/mffmbitstream/ Other Projects : http://sourceforge.net/search/?type_of_search=soft&words=mffm
