In this thesis, a new parallel synchronization mechanism, XTW, is proposed. XTW is designed for the parallel simulation of large logic circuits on a cluster of computer workstations. In XTW, a new event queue structure, XEQ, is created in order to reduce the cost of event-scheduling; a new message "un-sending" mechanism, "rb-messages", is proposed to reduce the cost of un-sending" previously sent messages. Both theoretical analysis and actual simulations provide evidence that XTW speeds up parallel logic simulations and provides excellent scalability versus the number of processors and the circuit size. An object-oriented parallel logic simulation software framework, XTWFM, is built upon the base of the XTW mechanism. A milliongates circuit, which can not be simulated by our sequential simulator, is successfully simulated by XTWFM over a cluster of 6 "small" PCs. This success demonstrates that a cluster of PCs is an attractive low-cost alternative for large scale circuit simulation.
