METHOD OF INDUCING OFF-CIRCUIT BEHAVIOR IN A PHYSICAL MODEL

A simulation model is provided which comprises a combination of software models and a hardware model. Induced off-circuit behavior of the hardware model during simulation is achieved by presenting it with off-circuit input patterns and sampling the resulting output patterns. After sampling, the hardware model is reset to its state prior to the presentation of the off-circuit patterns thereby causing the simulation to resume and preserving the integrity of the simulation.
