Popis: IR-Drop induced timing failures during testing can be avoided by minimizing the peak capturepower. This paper models the Capture-Power minimization problem as an instance of the Bottleneck Traveling Salesman Path Problem (BTSPP). The solution for the BTSPP implies an ordering on the input test vectors, which when followed during testing minimizes the Peak Capture-Power. The paper also presents a methodology for estimating a lower bound on the peak capture-power. Applying the proposed technique on ITC'99 benchmarks yielded optimal (equal to the estimated lower bound) results for all circuits. Interestingly, the technique also significantly reduced the average power consumed during testing when compared with commercial state-of-the-art tools.
