Setup check: The clock gating setup check isused to ensure the EN is are stable before the clock is active. A clock gating setup failure can cause a glitch at the leading edge of the clock. 2. clock gating hold check is used to ensure that the EN is stable while the clock is active...
Clock gating is an effective way of reducing the dynamic power dissipation in digital circuits. In a typical synchronous circuit such as the general purpose microprocessor, only a portion of the circuit is active at any given time. Hence, by shutting down the idle portion of the circuit, the...
We finally present the covering problem arising in a new method called look-ahead clock-gating, for which the question of whether the exact covering problem is easy or difficult is left open. 展开 关键词: Exact covering Perfect matching VLSI power minimization Clock-gating ...
In my lastblog, which received huge response, I talked a simple and efficient technique for clock gating. But it came with an additional cost of an extra clock gating setup and hold check. And the reason for those checks was, mainly, to get rid of unacceptable glitches in the EN pin. ...
Clock gating is a widely used technique for dynamic power reduction in VLSI design. In its most straightforward application it allows disabling the clock signal of a flip-flop once its state is no longer subject to changes. This paper extends this technique one step further and proposes a syste...

There is disclosed a method, and associated apparatus, for optimizing a gating expression for controlling the clock gating to a set of clocked state holding elements, said gating expression comprising at least one variable, the method comprising the step of maximizing the conjunctive form of said ...
A very efficient and easy to implement method to cut down energy losses in idle times is proposed, the so-called power-clock gating. The basic idea is to use a switch to disconnect the power-clock from the adiabatic circuit when no operations are performed in the system. The theory to po...
