Calypto Reduces Power Consumption by 60% with PowerPro CG

Calypto(TM) Design Systems Inc., the leader in sequential analysis technology, announced the immediate availability of PowerPro(TM) CG, which has reduced power by up to 60% on initial customer designs with no impact on functionality, area or performance.

PowerPro CG — for PowerPro Clock Gating — dramatically reduces power consumption by applying sequential analysis techniques at the register transfer level (RTL) to identify micro-architectural changes that result in a lower power circuit.

By analyzing the sequential behavior of synthesizable RTL designs across multiple clock cycles, PowerPro CG identifies regions of a chip that can be clock gated to reduce dynamic power. It then automatically generates the clock-gating enable logic, providing consistently better results in significantly less time than the error prone, time consuming manual techniques used by design teams today.

“PowerPro CG is a breakthrough product in the Electronic Design Automation market,” says Tom Sandoval, Chief Executive Officer of Calypto. “For our customers, achieving the lowest possible power consumption is a true competitive advantage, and sequential clock-gating at the RTL level is a critical step in achieving that goal.”

Unlike combinational power reduction tools, PowerPro CG identifies and generates sequential clock-gating transformations. By fitting into existing design flows with industry standard library, timing, and switching activity file formats, the power savings achieved by PowerPro CG are complementary and cumulative to optimizations performed by synthesis and placement tools downstream.

Introducing the PowerPro Product Family
PowerPro is Calypto’s latest product offering based on the company’s unique sequential analysis technology. The clock-gating capabilities in PowerPro CG incorporate power optimization engines with concurrent area, timing, and power analysis to enable a variety of clock-gating transformations that reduce dynamic power without negatively impacting leakage power.

PowerPro CG, the first product released in the PowerPro family, specifically targets the automation of sequential RTL clock-gating optimizations.

Availability and Pricing
PowerPro is available now and runs on PC platforms running Linux. It is priced at $295,000 (U.S. dollars) for a one year time-based license.
