With rapid improvements in design and simulation tools, designers are able to use an automatic logic synthesizer to create a circuit design which satisfies logic functions. Unfortunately, it may create testability problems, e.g., untested faults occur in the circuits. In some cases, aggressive circuit designers design a high performance or low cost circuit with tradeoffs which violate LSSD design rules. As a result, the circuits run well in the functional mode but fail in the testing environments.
