Abstract
The present invention is related to a method for testing a micro-electronic device, by applying a plurality of test vectors to said device, and measuring for each test vector, the quiescent supply current IDDQ, to said device, wherein each IDDQ measured value is divided by another IDDQ value, and wherein the result of said division is compared to a predefined reference, resulting in a pass or fail decision for said device.
