Abstract
An integrated circuit device includes scan chains and path margin monitor units (PMUs) on a single die. The scan chains test signal paths in the integrated circuit device. The PMUs include path monitor circuitry and self-test circuitry. The path monitor circuitry monitor delays of signals propagating along the signal paths. The self-test circuitry test the path monitor circuitry and report the test results via a communications path other than the scan chains.
