P2P and Rmap - new software tool for quick and easy verification of power nets

A new software tool, P2P, for electrical simulation of power nets is presented. The Rmap functionality of P2P calculates resistances from specified starting points to all points on the net, and visualizes the results in resistance color maps - which enables quick identification and debugging of layout errors. P2P also enables point-to-point resistance calculation, IR voltage drop analysis, and current density verification. Case studies are presented for overall power/ground net verification, and for specific tasks of guard ring and ESD device resistance and current density verification.
