Abstract
A method is provided to evaluate substrate noise propagation in an integrated circuit design, the method comprising: providing a tile definition that specifies an electrical model associated with instances of the tile; mapping a plurality of respective tile instances to respective locations of the substrate; obtaining respective waveforms indicative of digital switching induced power grid fluctuations associated with the respective identified contacts; and associating a voltage with a selected tile instance of the tile grid that is indicative of substrate noise injection due to waveforms associated with contacts encompassed by the selected tile instance.
