An Efficient Parallel Critical Path Tracing for Path Delay Fault Simulation

چکیده مقاله

Delay fault simulation is the most general method that is used to assess the quality of generated test sets. Path delay fault is one of the most frequently used delay fault models. Path delay fault simulation is a time-consuming operation, especially for today’s complex digital circuits. In this work, a novel critical path tracing algorithm is proposed for parallel path delay fault simulation. The obtained outcomes denote 489 times average speedup compared with the traditional path tracing, as well as 186 times average speed-up in comparison with the latest reported results of previous studies.
