Even though there has been a considerable effort in proposing weighted random pattern testing schemes over the years, insufficient attention has been devoted to their implementation. This paper describes the design details, operation, cost, and performanceof a distributed weighted pattern test approach at the chip level.The traditional LSSD SRLs are being replaced by WRP SRLs designedspecifically to facilitate a weighted random pattern (WRP) test.A two-bit code is transmitted to each WRP SRL to determine itsspecific weight. The WRP test is then divided into groups, where eachgroup is activated with a different set of weights. The weights aredynamically adjusted during the course of the test to “go after” the remaining untested faults.The cost and performance of this design system are explored on ten pilot chips. Results of this experiment are provided in the paper.
