  • Testing of circuits with multiple clock domains
    Publication number: 20070186132
    Abstract: A circuit under test (24) has a scan chain comprising flip-flop cells (IOa-c) with inputs and outputs operationally connected to the logic circuits (12). Different clock domains each contain a respective part of the flip-flop cells (10a-c) that are clocked by a respective domain clock signal (CLKa, CLKb, CLKc). A set of test input patterns is selected, each with an associated combination of domain clock signals that will be selectively enabled to capture a response to the test pattern.
