Anyway, I would welcome any help New simulation examples are following here. Only the legacy format appears to have official documentation and some third party documentation. Sep 12, 2023 · more or less V6 (or older) Opamp-Spice-Model. For example, a search for “model transformer in pspice” turns up this: SPICE has no model for an ideal transformer. include filename missing” So far Currently the following types of documents can be imported standalone. I’m new to KiCad, but I have been able to search several standard Spice libraries with no luck. After a little study of the original SPICE syntax, most of the SPICE model files intended for a particular version of SPICE can be converted to other versions. KiCad integrates the open source spice simulator ngspice to provide simulation capability in graphical form through integration with the Schematic Editor. 1 reverted back to semiconductors due to convergence issues].
