    摘要: A method, system and computer program product for modeling and simulating a powergated hierarchical element of an integrated circuit is disclosed. In modeling a powergated macro, the invention does not model all logic gates or elements as powergated, instead, the invention only models latches as connected to an integrated switch to be powergated. In addition, a fence circuit attached to the powergated macro is modeled as including an extra control signal to force a powergated state of the powergated macro into the fence circuit.

    摘要: A power gate includes a series of electrical contacts along at least a portion of an integrated circuit and a series of power gate transistors electrically coupled to the electrical contacts on the integrated circuit to form a power gate boundary, e.g., at the integrated circuit periphery. The electrical contacts along at least a portion of a running length of the power gate boundary define a substantially non-linear profile. The non-linear profile provides increased contact density which improves current balancing across the electrical contacts and current throughput through the power gate. The non-linear profile is a sinusoidal or zigzag pattern with intermediate offset bump contacts. The contact profiles along the power gate boundary can include both linear and non-linear profiles.

    摘要: Power supply variations and jitter are measured by monitoring the performance of a ring oscillator on a cycle-by-cycle basis. Performance is measured by counting the number of stages of the ring oscillator that are traversed during the clock cycle and mapping the number of stages traversed to a particular voltage level. Counters are used to count the number of ring oscillator revolutions and latches are used to latch the state of the ring oscillator at the end of the cycle. Based on the counters and latches, a monitor output is generated that may also incorporate an adjustment for a reset delay associated with initializing the ring oscillator and counters to a known state.
