Easy-to-Use EM-IR Flow Enables Full-Chip Verification

The Cadence Voltus-XFi Custom Power Integrity Solution is a transistor-level electromigration and IR drop (EM-IR) tool that delivers foundry-supported SPICE-level accuracy for power integrity signoff.

EM-IR presents unique challenges at the transistor level, from complex EM rules to the high costs of simulating for current on a large RC network at post-layout. Enabled via an integration with the Cadence Spectre X SPICE Simulator and the Virtuoso Design Platform, the Voltus-XFi solution accelerates power signoff analysis and closure.
