Abstract:
A method of simulating an integrated circuit which includes a plurality of conductive nets that are electrically separate from each other, which includes a device having a plurality of conductive first sections that are each part of a respective said net, and which includes a conductive second section external to said device, said second section being part of one of said nets which includes one of said first sections, said method comprising the step of determining a set of capacitances associated with said device by:subdividing at least one of said nets on a theoretical basis to identify a plurality of net portions that collectively define said at least one of said nets so that said first and second sections are allocated to different said net portions; treating said net portions as theoretically electrically separate from each other, while identifying respective capacitances between each said net portion and each of the other net portions; discarding selected ones of said capacitances; and determining each of the remaining ones of said capacitances of said set by summing the capacitances which have been identified between each of said net portions of one of said nets and a net portion of a further said net.
