External module definition to support direct import of SPICE netlists in Annex E.Currently this is not clearly stated in the LRM.
Augment external module and macromodule definitions within a simulator class. Extend the external module syntax with parameters indicating the language used. Also, case sensitivity of SPICE simulators should be accounted for in the language. Should there be filters for support of foreign language? Implement something similar to shell which is used in digital simulators.
