Abstract
An integrated circuit programmable logic device comprising: a plurality of programmable logic elements that are responsive to clock signals; a clock signal generation circuit which produces a first clock signal; a first phase shifting element which produces a second clock signal which is a phase-shifted version of the first clock signal, shifted in phase by an amount which compensates for a logic signal delay; and a clock signal distribution network which distributes the first and second clock signals among the programmable logic elements.
