Abstract
A computer program product for calculating a path delay in static timing analysis (STA) for a circuit design includes determining a connectivity between a first device and a second device in a path of the circuit design, generating a delay constraint associated with the first device and the second device based on the connectivity, the delay constraint specifying a correlation between a first device delay of the first device and a second device delay of the second device, and calculating a path delay of the path based on the first device delay and the second device delay that satisfies the delay constraint.
