Abstract
Additional circuitry is included in an input cell design structure for an integrated circuit to detect and report transitions on an input that was expected to be stable, and to store that event for later analysis. Two or more modified input cells may have their error indications daisy-chained together to minimize additional routing. The storage elements may be included in a scan chain to allow for isolation of which input had the unexpected transition.
