Abstract
A method is taught for determining a calibrated wire load model. The calibrated wire load model can be used to reach timing closure for an integrated circuit. The method includes; determining a reference timing description; determining a wire load model based on synthesis; determining a wire load model based connectivity; comparing the wire load model based on connectivity to the reference timing description. The method teaches adjusting the wire load model based on connectivity to determine a wire load model which faciliates timing closure. The method also teaches comparing the wire load model (based on synthesis) with the reference timing description. The disclosure contemplates a computer program product based upon the method taught. The disclosure further contemplates an integrated circuit designed based on the method taught. In another embodiment a computer system or another electronic system includes an integrated circuit designed by the method taught.
