Abstract

We present a test resource partitioning (TRP) technique that simultaneously reduces test data volume, test application time and scan power. The proposed approach is based on the use of alternating run-length codes for test data compression. Experimental results for the larger ISCAS-89 benchmarks and an IBM production circuit show that reduced test data volume, test application time and low power scan testing can indeed be achieved in all cases.
