Abstract
A digital system simulation apparatus and method enable a user to interactively control, during simulation, the sampling of signals in the digital system whose behavior is being simulated. The behavior of the system can be approximated better by recognizing and allowing a precise definition of element outputs even though the element inputs can include undefined variables. The apparatus allows efficient and better utilization of system memories by providing the capability of defining multiple outputs of the circuit elements in a single instruction when those outputs all have common inputs.
