WebDec 21, 2016 · Description. Design for test (DFT) is also important in low-power design. To increase test coverage, ensure that the clock-gating logic inserted by the low-power engine is controllable and observable. First, select a clock-gating cell that contains test control logic, indicating whether the test control logic is located before or after the latch. WebIf we are able to cancel gating work or it wasn't scheduled, hold the clock reference count until scaling is in progress. If gate work is already running in parallel, let's skip the frequecy scaling at this time and it will be retried once next scaling window expires.

In computer architecture, clock gating is a popular power management technique used in many synchronous circuits for reducing dynamic power dissipation, by removing the clock signal when the circuit is not in use or ignores clock signal. Clock gating saves power by pruning the clock tree, at the cost of … See more An alternative solution to clock gating is to use Clock Enable (CE) logic on synchronous data path employing the input multiplexer, e.g., for D type flip-flops: using C / Verilog language notation: Dff= CE?
