Abstract
An integrated circuit (IC), including a clocking system, a plurality of clock gate controllers, and a plurality of clock gates, is provided. During a capture phase of an at-speed testing of the IC, the clocking system generates an at-speed clock signal including launch and capture pulses that are extracted from a reference clock signal based on a capture phase frequency. The plurality of clock gate controllers generates a plurality of enable signals such that for the launch pulse, one enable signal is asserted, and for the capture pulse, the same or different enable signal is asserted. Each of the plurality of clock gates is activated based on an assertion of a corresponding enable signal. Further, during the capture phase, one or more activated clock gates enable the at-speed testing of the IC based on the at-speed clock signal.
