Abstract

A circuit device is provided with a first codec including a first portion of a logic circuit and a second codec including a second portion of the logic circuit. The circuit device can also include a plurality of first scan chains coupled to the first codec and configured to shift a delayed test vector onto the first codec, wherein the delayed test vector is a test vector with a phase delay. A plurality of second scan chains can be coupled to the second codec and configured to shift the test vector onto the second codec.
