System and method for synchronization of multiple analog servers on a simulation backplane

摘要

A multiprocessor system and method are provided for simulating electrical circuits. The circuit is divided into portions, and separate simulator modules perform a multi-rate behavior simulation, to simulate the performance of respective circuit portions. The simulator modules communicate using block waveform relaxation. Accordingly, the amount of inter-process communication is advantageously low, and the need for backing up digital simulation processes is avoided, providing advantageously fast performance. A system according to the invention is preferably implemented, either physically or logically, in a simulation backplane configuration, having a common connective bus structure, to which multiple active simulation modules are coupled through an interface which is standardized for facilitating block waveform relaxation.
