Distributed approach for parallel exact critical path tracing fault simulation

Distributed computing attempts to aggregate different computing resources available in enterprises and in the Internet for computation intensive applications in a transparent and scalable way. Fault simulation used in digital design flow for test quality evaluation can require a lot of processor and memory resources. To speed up simulation and to overcome the problem of memory limits in the case of very large circuits, a method of model partitioning and the procedure of parallel reasoning for several distributed simulation agents was proposed. The concept and implementation of web-based distributed system was introduced.
