19. The computer program product of claim 17 further comprising: code for creating multiple copies of the circuit component, wherein representations of a lower-level circuit instance vary from one branch to another branch due to at least out-of-module-reference, automatic inserted connection module, Verilog-AMS defined parameter, or VHDL-AMS package reference; and code for representing the design using the multiple copies of the circuit component.
