Patent ID: 8843864

Claim:
A computer-implemented method of performing statistical static timing analysis (SSTA) comprising: calculating a parametric arrival time of a data signal transmitted via a data path including a plurality of cells the parametric arrival time determined through an arrival time nominal value and an arrival time standard deviation value; calculating a parametric required time of the data signal based on a clock signal transmitted via a clock path, the parametric required time determined through a required time nominal value and a required time standard deviation value; calculating a corner slack value based on the parametric arrival time and the parametric required time, the corner slack representing an amount of time between an arrival time of the data signal and an arrival time of the clock signal; and determining, by a computer, specific delay shift values for a subset of the plurality of cells in the data path, such that a sum of the specific delay shift values of the plurality of cells matches the corner slack value.
