System and method for estimating capacitance of wires based on congestion information |
摘要 |
A system for calculating interconnect wire lateral capacitances in an automated integrated circuit design system subdivides the chip area of a circuit design to be placed and routed into a coarse grid of buckets. An estimate of congestion in each bucket is computed from an estimated amount of routing space available in the bucket and estimated consumption of routing resources by a global router. This congestion score is then used to determine the spacing of the wires in the bucket which is in turn used to estimate the capacitance of the wire segment in the bucket.
