Of late some interesting and useful work has been done onthe problem of testing logic surrounding embedded memories. This workassumes that the logic surrounding the memory is functionallypartitioned and that the different partitions are logically isolatedone from the other. This paper expands upon past work using a moreflexible design rule which allows feed-forward connections betweenthe data-path Prelogic and Postlogic. The connections are such thatthere is no feedback from the memory outputs to its inputs, and boththe Prelogic and the Postlogic are disconnected from theAddress and Control logic. Under this design rule we show theauxiliary circuits used to determine the random patterntestability of faults in the circuitry driving the address inputsand the controls of the two-port memory. The techniquesdescribed herein are intended to be used in conjunction with thecutting algorithm for testability measurement in built-in self-test(BIST) designs, but may also be suitable for use with other detectionprobability tools and simulation tools.
