I have been looking for a way to simulate multi-unit symbols in KiCad, and there seems to be no way to associate a spice model with a multi-unit symbol. Is this true?
There is a thread in the kicad-developers team mailing list archive entitled “Re: SPICE and multi-unit parts” Message #35583 where this problem is also discussed. They describe the issue as being a problem of one-to-one mapping between symbol and spice model, whereas it should be one-to-many.
One way this might be implemented is to treat units of a symbol as if they were unique components. A spice model associated with a symbol having N units must contain N elements of type ‘SUBCKT’. The first in the file would be associated with symbol Unit-A, the second with Unit-B and so on. Does this seem like a viable approach?
Or is this somehow already supported and there exists some undocumented way to simulate multi-unit symbols with spice?
