ABSTRACT:
An integrated circuit includes a first clock island, a second clock island, a clock generator, and a first programmable delay element. The first clock island is configured to receive a first clock signal. The second clock island is configured to receive a second clock signal. The clock generator is configured to provide a generated clock signal and the first and second clock signals are based on the generated clock signal. The first programmable delay element is coupled between the clock generator and the first clock island. The first programmable delay element is configured to receive the generated clock signal and provide the first clock signal. The integrated circuit is configured to account for a clock skew between the first and second clock signals when information is transferred between the first and second clock islands. In this manner, a predetermined amount of the clock skew may be introduced between the first and second clock signals to smear out, over time, instantaneous power supply current demands of respective logic within the first and second clock islands.
