Abstract:
A timing analysis method evaluates a performance of a target circuit that is to be designed, and includes calculating a correlation coefficient r between two arbitrary macro cells that are coupled and form the target circuit based on layout information including an arrangement of macro cells forming the target circuit and correlation information indicating a correlation between two macro cells that are coupled for each of arrangements of macro cell pairs, calculating a distribution function σ of a standard deviation of delay times of the two arbitrary macro cells based on the correlation coefficient σ, and carrying out a statistical timing analysis of the target circuit based on the correlation coefficient r and the distribution function σ of the standard deviation with respect to each of the macro cell pairs forming the target circuit.
