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 ...

WebSep 16, 2004 · This is achieved by forcing clock-gating logic into an enabled state. Inserting any extra test control signals into the clock-gating logic will prohibit the ATPG tool from fully testing the clock control logic in the functional path.
