Abstract: A method for testing at least one logic block of a processor includes, during execution of a user application by the processor, the processor generating a stop and test indicator. In response to the generation of the stop and test indicator, stopping the execution of the user application and, if necessary, saving a state of the at least one logic block of the processor. The method further includes applying a test stimulus for testing the at least one logic block of the processor. The test stimulus may be shifted into scan chains so as to perform scan testing of the processor during normal operation, such as during execution of a user application.

Abstract: An automated process for designing a memory having row/column replacement is provided. In one embodiment, a potential solution array (50) is used in conjunction with the row/column locations of memory cell failures to determine values stored in the actual solution storage circuitry (92). A selected one of these vectors stored in the actual solution storage circuitry (92) is then used to determine rows and columns in memory array (20) to be replaced with redundant rows (22, 24) and redundant columns (26).
