Voltus-Fi Custom Power Integrity Solution

Cadence^® Voltus^™-Fi Custom Power Integrity Solution is a transistor-level electromigration and IR-drop (EMIR) tool that delivers foundry-certified SPICE-level accuracy in power signoff. 

EMIR 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 our Spectre^® Accelerated Parallel Simulator signoff SPICE simulation solution, Voltus-Fi Custom Power Integrity Solution shortens power signoff closure and analysis through:

• Our patented voltage-based iteration method, which calls for a smaller memory footprint and runs faster than the industry's traditional current-based iteration method. In the first stage, a RC reduced simulation is run to collect the voltage profile at tap device points. Then, the collected profile is applied to the entire RC network to simulate all sub-node states for voltage/current and to generate EMIR reports.
• Integration with our Virtuoso^® platform, providing a single design flow for better productivity in the analog and custom block EMIR signoff process
• Integration with Voltus IC Power Integrity Solution, resulting in a seamless flow for advanced analog/mixed-signal power signoff for designs that have mixed transistor-level and cell-level blocks

Fastest Design Closure Flow

The combined use of Voltus-Fi Custom Power Integrity Solution and Voltus IC Power Integrity Solution, tightly integrated with several other Cadence tools, provides the industry's fastest design closure flow.
