Abstract

Many systems-on-a-chip (SOCs) include processors as central units to implement diverse algorithms and control peripheral units such as embedded cores. The computing power of the embedded processor can be used to self-test its own functions as well as to test the other cores within the chip boundary. In BIST methodology, pseudo-random pattern testing can reduce the memory requirements. In addition to general pseudo-random pattern testing, this paper proposes and evaluates a novel selective-random pattern test technique. This technique increases the fault coverage while significantly reducing test application time. This also greatly decreases the memory requirements compared to traditional BIST schemes. The cost for extra hardware is low and the technique is easily integrated with parallel scan and boundary scan designs.
