ABSTRACT
We present a new methodology for current driven routing and layout verification for analog applications used to avoid defects due to electromigration.The methodology presented uses a commercial simulator to calculate the current flow at all terminals of the analog circuit. Afterwards maximum currents per terminal are extracted and used as guidance for the Current Driven Router (CDR) which is capable of routing analog multiterminal signal nets with current driven wire widths.The Current Density Simulator (CDS) is used to compute and verify current densities in layouts that were generated using a 'standard' routing methodology.
