It is USUALLY the case that you can go from Berkeley SPICE to another SPICE. That is, a netlist that was written for a "generic" SPICE, often can run with no modification on a commercial SPICE program. But as Fred Balistreri says, controlled sources often differ. This is true even between one "generic" Berkeley SPICE and another. SPICE3 dramatically changed the format of controlled sources, and Berkeley wrote application notes about converting a SPICE2 netlist to run under SPICE3. Nodenames also differ. SPICE2 had only numeric nodenames. Many other SPICE programs allow non-numeric nodenames, perhaps in different ways.
