Abstract

A logic array block of a programmable logic device includes a clock generation circuit. The clock generation circuit has an input node to receive a clock signal, an enable signal input node to receive an enable signal, a clock generation circuit output node, and a digital logic circuit connected between the clock generation circuit input node, the enable signal input node, and the clock generation circuit output node. The digital logic circuit generates an enabled clock signal on the clock generation circuit output node in response to the clock signal and the enable signal when the enable signal has been asserted during a previous clock state of the clock signal. A set of logic elements, each of which includes a logic element clock input node, is connected to the clock generation circuit output node such that each logic element of the set of logic elements receives the enabled clock signal from the clock generation circuit.
