ANSYS RTL Power Model

ANSYS introduced RTL Power Model (RPM). Their technology helps engineers optimize a wide range of power-sensitive applications. It bridges the power gap from register transfer language (RTL) design to physical implementation. RPM accurately predicts integrated circuit (IC) power behavior at the RTL level with consideration for how the design is physically implemented. RTL Power Model enables chip power delivery network (PDN) and IC package design decisions early in the design process.

RPM is a new offering to Apache’s PowerArtist-XP software. RTL Power Model’s core technologies include PowerArtist Calibrator and Estimator (PACE) for accurate power estimation at the RTL level prior to availability of physical layout. Compared to traditional wire load models tuned for timing closure, PACE uses proprietary data-mining and pre-characterization techniques to create higher-quality power and capacitance models. By factoring in various circuit types, PACE determines RTL power within 15% of gate-level power.

RTL Power Model also includes Fast Frame-Selector for critical power-aware cycle selection. Fast Frame-Selector technology performs power analysis on RTL simulation vectors and selects a set of the most power-critical cycles to use throughout the design flow, from early design planning to final chip sign-off. It can accurately identify a few cycles representing the transient and peak power characteristics from millions of vectors within hours.
