Abstract
An integrated circuit includes a test block which in turn includes a plurality of identical paths; a counter selectively coupled to the plurality of identical paths to selectively obtain a count of at least one of correctly operating paths and incorrectly operating paths from each of the plurality of identical paths; and a plurality of count latches selectively coupled to the counter to store output of the counter. Each path in turn includes a first clocked latch; a clocked logic path beginning and ending at the first clocked latch; and a clocked detection circuit coupled to the first clocked latch and the counter, which determines whether the clocked logic path is operating properly in a given clock period.
