Abstract
A system and method are provided for generating a structurally-aware timing model for operation of a predetermined circuit design. The timing model is generated to have a plurality of timing arcs representing timing characteristics of the circuit design. Additionally, terminal pairs of the circuit design are evaluated to determine characteristic structural weights for selected paths through the circuit design. The structurally-aware timing model may then be incorporated into a top-level hierarchical circuit design for timing analyses and pessimism removal to arrive at realistic timing characteristics. The structural weights are particularly helpful in an AOCV-type pessimism removal post-process.
