Abstract:
A circuit includes a false circuit path in a circuit under test having a starting logic point to an end logic point of the path. The false circuit path is designated as a testing path to be excluded during testing of one or more valid timing paths of the circuit under test. A false path gating circuit gates the starting logic point to the end logic point of the false circuit path. The false path gating circuit disables the false circuit path in response to one or more gating controls asserted during the testing of the one or more valid timing paths of the circuit under test.
