METHODS AND SYSTEMS TO CONTROL POWER GATES DURING AN ACTIVE STATE OF A GATED DOMAIN BASED ON LOAD CONDITIONS OF THE GATED DOMAIN |
摘要 |
Methods and systems to adjust a resistance between a supply grid and a power-gated grid during an active state of a power-gated circuitry in response to load changes in the circuitry to maintain a relatively consistent IR droop. Subsets of power gates (PGs) may be selectively enabled and disabled based on changes in a load factor, such as a voltage, which may be monitored at a gated power distribution grid and/or proximate to a transistor gate within the power-gated circuitry. The adjusting may be performed to minimize a difference between the monitored voltage and a reference, such as with successive approximation or CMS software. PG subsets may be distributed within one or more layers of an integrated circuit (IC) die and may be selectively enabled/disabled based on location. PGs may be embedded within lower layers of an integrated circuit (IC) die, such as within metal layers of the IC die. |
