Abstract

A system and method for providing a static mode for logic circuits with dynamic latches. The invention provides a reliable static mode for testing of the logic circuit, prevents "through current" power consumption when clocks to the logic circuit are stopped, and allows the circuit to be powered down when idle. The system includes a circuit for forcing clock phases to an active state, a circuit for breaking feedback paths within the logic circuit, and an optional clock loss detector for detecting clock inactivity and automatically initiating the static mode.
