Abstract:
A system for testing multi-clock domains in an integrated circuit (IC) includes a plurality of clock sources coupled to a plurality of clock controllers. Each of the clock sources generates a fast clock associated with one of the multi-clock domains. Each of the clock controllers is configured to provide capture pulses to test one clock domain. The capture pulses provided to a clock domain are at a frequency of a fast clock associated with the clock domain. The clock controllers operate sequentially to provide the capture pulses to test the clock domains.
