ABSTRACT:
Computer-aided design tools analyze a custom logic design for a programmable logic device integrated circuit. The tools identify distinct clock domains in the design. The tools also identify which of the clock domains are synchronous. The tools examine the synchronous clock domains to determine which of the clock domains have required fixed phase relationships. Clocks for clock domains that do not have required fixed relationships can be adjusted in phase to minimize power supply simultaneous switching noise. Noise may be minimized by making clock phase adjustments using a programmable phase-locked loop circuit.
