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.
