Abstract
A generalized hardware architecture that supports built-in self testing (BIST) for a range of different computer memory configurations and a generalized BIST algorithm can be compiled, based on specified configuration characteristics (e.g., the number of write ports, the number of read ports, the number of entries, and the number of bits per entry in the computer memory), to generate the hardware design for a particular computer memory system. In one embodiment, the generalized hardware architecture includes a multiplexer block that enables a single BIST comparator to be multiplexed for use in performing BIST testing via different read ports of the computer memory.
