Abstract: A methodology for evaluating the fault coverage of RAM test algorithms is proposed and the architecture of a flexible software analysis program is described. The analysis, performed for arbitrary test sequences, provides a comprehensive set of coverage statistics for functional cell-array faults. An overview of the analysis capabilities of the program is given, the fault state transition conditions for several representative fault classes are specified, and coverage analyses results for a variety of test algorithms are presented.
