Mixed-level simulation with a Zycad simulation engine

A mixed behavioral- and gate-level simulator is described. The unique feature is that the gate-level modules of a design are simulated using a simulation engine, while a host computer simulates the behavioral-level modules and enforces the synchronization between the host computer and engine. The behavioral models are described using a high-level process-oriented behavioral specification language BSL. Runtime experiments show that the simulator speeds-up the simulation of systems of size ( Hash gates, Hash lines BSL) in ((25 K, 2 K), (50 K, 10 K)) by a factor of 5-7 times, compared to the compatible software simulator.<>
