Abstract
A system, method, and computer program product for extending device model parameter specification flexibility when using a subcircuit wrapper. Embodiments facilitate device modeling by allowing a modeling engineer to eliminate the explicit specification of a large set of wrapped device instance parameters as parameters to the subcircuit wrapper itself. A circuit designer may now use the subcircuit wrapper to specify an instance of the subcircuit without having to explicitly provide values for all such parameters. The simulator program's built-in device model calculates its default parameter values, which are often the result of complex expressions involving the other parameters, resulting in more accurate simulations. Subcircuit wrappers no longer need to be explicitly regenerated when a new version of the wrapped device model becomes available for the simulator (e.g., one that supports additional instance parameters that were not present on the earlier version when the subcircuit wrapper was created).
