Abstract: A layout effect characterization circuit includes a plurality of inverting device chains including a reference chain and one or more chains having a different inverting device arrangement and a same number of inverting devices per chain. A low pass filter is coupled to an output of the inverting device chains to produce a filtered output. An output capture circuit is coupled to the filtered output to enable a comparison of a captured filtered output of the one or more chains having the different inverting device arrangement to a captured filtered output of the reference chain.

Abstract: A mechanism is provided for efficiently recycling a charge from a power domain that is discharging. A side of a discharging power domain normally coupled to a voltage supply is disconnected from the voltage supply. The side of the precharging power domain normally coupled to the voltage supply is currently disconnected from the voltage supply. The side of the discharging power domain normally coupled to the voltage supply is connected to a side of the precharging power domain normally coupled to the voltage supply. A side of the discharging power domain normally coupled to the ground is disconnected from ground. The side of the discharging power domain normally coupled to ground is connected to the voltage supply, thereby precharging the precharging power domain with the charge from the discharging power domain that would normally be lost due to leakage.

Abstract: A system for layout effect characterization of an integrated circuit includes a memory having computer readable instructions and a processor for executing the computer readable instructions. The computer readable instructions include selecting an adjustable clock setting of an input clock for a layout effect characterization circuit of the integrated circuit and enabling a predetermined duty cycle of the input clock to pass through a plurality of inverting device chains including a reference chain and one or more chains having a different inverting device arrangement and a same number of inverting devices per chain. The computer readable instructions also include measuring a captured output of the one or more chains having the different inverting device arrangement and a captured output of the reference chain.
