Abstract
A statistical single-input switching (SIS) timing value is obtained for a first input of a device. A side input with an arc to a common output of a circuit is selected and a statistical skew for the first input and the selected side input of the circuit is obtained. An expected-value for a statistical scale factor distribution is convolved and computed based on the statistical skew. The statistical single-input switching (SIS) timing value is scaled with a final effective statistical scale factor based on the expected-value; optionally, sensitivities of the statistical timing value to variational parameters are chain-ruled with the sensitivities of the statistical skew to variational parameters; and a statistical timing analysis of a given VLSI design is generated based on the scaled (and optionally, chain-ruled) statistical single-input switching (SIS) timing value to create the improved VLSI circuit design.
