Due to extensive ultra-low-power requirements and shortened design cycles, it is critical to make power design trade-offs, such as dynamic voltage/frequency scaling, clock-gating/power-gating schemes, and package selection, early in the design cycle, when changes are easier to make and have less impact on schedule or cost.
"Apache's innovative approach provides a complete front- to back-end power analysis flow," said
As a new offering to Apache's PowerArtist™-XP software, RPM's core technologies include PowerArtist Calibrator and Estimator (PACE™) for accurate power estimation at the RTL level prior to availability of physical layout as well as Fast Frame-Selector for critical power-aware cycle selection.
PACE uses proprietary data-mining and pre-characterization techniques to create higher-quality power and capacitance models, as compared to traditional wire load models tuned for timing closure. By considering characteristics for various circuit types, such as combinational logic and sequential elements, PACE delivers RTL power within 15 percent of gate-level power, leading to more cost-effective and higher-quality results.
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, improving productivity and ensuring power sign-off integrity.
RPM enables a comprehensive power methodology from early design to sign-off by providing physical-aware RTL power data. Apache's RedHawk™ leverages RPM to perform PDN prototyping then generates an early-stage
"The introduction of RPM demonstrates Apache's continued commitment to delivering innovative key technologies that address the critical low-power design challenges," said
Low-Power Application Optimization
Designing for low-power applications requires a methodology that addresses power budgeting and allows timely cost-sensitive decisions related to power. PowerArtist-XP software with RPM technology is ideal for advanced node designs of low-power applications including mobile, green computing, and consumer electronics devices. It helps bridge the gap from front-end RTL design to physical power sign-off, with more predictable accuracy, increased operating performance, and greater reliability for 28nm and below designs.
