ABSTRACT:
To estimate path delays within an IC, a serial database is first created to hold and read out RC extraction data for nets within the IC in an order in which the RC extraction data will be needed when estimating path delays. Thereafter, as the RC extraction data is sequentially read out of the database for each net, the path delay though each section of the net is computed and added to the estimated path delay for each signal path including that net section. The RC extraction data for each net is accessed and accessed only once, thereby minimizing the processing time needed to perform timing analysis by minimizing hard disk read accesses when the RC extraction database resides on a hard disk.
