Web6. Power Gating. A logical extension to clock gating is power gating, in which the power or supply voltage to circuit blocks not in use are temporarily turned off. Typically the supply voltage is cut off by logic equivalent to switch, controlled by the Power Management Unit. Power gating is possible by realizing multiple power domains in the ... Webaggressive clock gating and analysis of target technologies without the need to lower the voltage levels of specific portions of the design (multi-voltage). If a only a single voltage level is necessary, but using a power-down portion of the design is desired, this is known as a multi-supply design. This is an attractive design model for our goals.
