Abstract

Test and validation of embedded array blocks remains a majorchallenge in today‘s microprocessor design environment. The difficulty comesfrom twofold, the sizes of the arrays and the complexity of theirtiming and control. This paper describes a novel test generation methodology for test and validation of microprocessor embedded arrays.Unlike traditional ATPG methods, our test generation method is based upon the high-level assertion specification which is originally used for the purpose of formal verification. The superiority of these assertion tests over the traditional ATPG tests will be discussed and shownthrough various experiments on recent PowerPC microprocessor designs.
