A CO-SIMULATION ENVIRONMENT FOR MIXED SIGNAL, MULTI-DOMAIN SYSTEM LEVEL DESIGN EXPLORATION

This thesis presents a system-level co-simulation environment for mixed domain design exploration. By employing shared memory IPC (Inter-Process Communication) and utilizing PDES (Parallel Discrete Event Simulation) techniques, we examine two methods of synchronization, lock-step and dynamic. We then compare the performance of these two methods on a series of test systems as well as real designs using the Chatoyant MOEMS (Micro-Electro Mechanical Systems) simulator and the mixed HDL (Hardware Description Language) simulator from Model Technology, ModelSim. The results collected are used to ascertain which method provides the best overall performance with the least overhead
