It depends what you are doing. You could make your own macromodel based on the specs, to whatever detail you need. In my experience, most people who ask about things like this don't need much detail. Most models are only valid in certain situations anyway. You need to verify the suitability of whatever model you use. In most situations, you can probably get away with modeling the power supply as a voltage source, but if you want to model signal coupling through the power supply, maybe the fancy model you download isn't good enough. > Are there certain manufacturers that are known to provide > SPICE models for their comonents? There are lots of kinds of models. Most manufacturers provide something for most parts. It is up to you to decide whether those models fit your needs. _______________________________________________ geda-user mailing list [email protected] http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
