Abstract :
A novel scheme for reducing the test application time in accumulator-based test-pattern generation is presented. The proposed scheme exhibits extremely low demand for hardware. It is based on a decoder whose inputs are driven by a very slow external tester. Experimental results on ISCAS benchmarks substantiate a test-time reduction of 75%-95% when compared to previously published test-set embedding approaches for accumulator-based test generation.
