Abstract:
1. A method for analyzing an electrical characteristic of a simulation of wire segments configured as a plurality of power meshes to be used in an integrated circuit (IC) core, comprising the steps of: (A) specifying a network of power busses corresponding to said power meshes; (B) specifying at least one type of analysis to be performed, wherein said analysis comprises (i) generating during said analysis a first file corresponding to said IC core in a format compatible with an electronic circuit simulator and (ii) calculating said electrical characteristic of said wire segments via said electronic circuit simulator, wherein (i) said IC core as represented in said first file comprises (a) one or more capacitance zones and (b) a plurality of pad cells connected to respective ones of said power meshes and (c) one or more power zones, (ii) each of said power meshes resides on a different conductive layer of said IC core, (iii) each of said power zones is bounded between a respective two horizontal busses of said power busses and a respective two vertical busses of said power busses in a respective one of said power meshes and (iv) each of said capacitance zones comprises (a) a respective capacitance value, (b) a respective physical orientation and (c) a respective physical width; (C) displaying said electrical characteristic as calculated to a user; (D) allowing said user to vary (i) a plurality of package and wire bond resistances connected to said pad cells, (ii) a plurality of package and wire bond capacitances connected to said pad cells and (iii) a plurality of package and wire bond inductances connected to said pad cells via a graphical user interface; and (E) allowing said user to vary respective current values within said power zones via said graphical user interface.
