ARM and ArchPro have announced success in a joint R&D project to validate advanced multi-voltage power management design techniques. Employing ARMR Intelligent Energy Manager (IEM) technology and validated with ArchPro's Multi-Voltage Simulator Tool (MVSIM) resulted in an EDA tool for pre-tapeout verification of power-managed designs.

The project produced working 65nm silicon for a complex reference SoC design jointly verified by the two companies. The SoC used an ARM processor with IEM technology demonstrating a number of active and sleep modes, to vary power and performance.

"MVSIM has proven its ability to verify sophisticated voltage schemes prior to tapeout and it is a verification solution applicable to a variety of multi-voltage schemes, including adaptive voltage scaling, power gating, and back bias," said John Goodenough, director of design technology at ARM. "We expect the ARM Partner community can benefit by leveraging this work as a reference."

According to the press release, IEM technology-based IP can save costumers up to 60 per cent battery life using adaptive clock frequency and voltage scaling. MVSIM enables IEM technology-based IP users to verify sophisticated voltage control schemes before tapeout. To validate MVSIM's capabilities, the two companies successfully collaborated on the verification of a reference 65nm SoC design using an ARM processor and the ARM Intelligent Energy Controller (IEC).

MVSIM enables users to make system-level architectural decisions at RTL related to multi-voltage techniques, including dynamic voltage scaling, power gating and back bias. MVSIM works with mainstream simulators like ModelSim, NC-Sim and VCS, enabling users to verify multi-voltage designs at the RTL level. There is no restriction on how the islands are organised. MVSIM supports any arbitrary partition in the hierarchy, including nested islands and domains.
