The prevalidated power-grid libraries will provide SoC designers with direct access to the hierarchical verification approach introduced with the latest version of VoltageStorm SoC, while maintaining the transistor-level accuracy required for deep-submicron power-integrity analysis, the company said. Once largely considered a second- or third-order effect, IR or voltage drop has become a first-order problem, according to Simplex and its partners.

Intellectual-property vendors can package the power-grid characterization libraries with their IP to facilitate VoltageStorm SoC verification and ensure customers are designing IR-drop-compliant systems-on-chip. "If the libraries are supplied with the cores, it makes it much easier for the user to implement these blocks," said Janet Greene, senior marketing manager with Simplex. Further, "VoltageStorm SoC comes with the tools and instructions to let designers create these libraries for their own blocks."

Prevalidated power-grid libraries will be available to ARM's foundry partners by the end of the year for select cores in the ARM9 family of 32-bit embedded RISC processors. The prevalidated power-grid libraries are available by request to Virtual Silicon's customers for select standard-cell libraries. Greene said Simplex is in negotiations to add partners to the program.Visit www.simplex.com, www.virtual-silicon.com and www.arm.com.

Programmable-core vendor Adaptive Silicon says it has successfully fabricated and qualified its MSA 2500 test chips on Taiwan Semiconductor Manufacturing Co.'s 0.18-micron process. The Los Gatos, Calif., company said the core is 100 percent functional on TSMC silicon, enabling the manufacture of systems-on-chip with the technology at that foundry. Adaptive has previously qualified its core-which enables placement of programmable-logic blocks on standard-cell SoC devices-on LSI Logic processes.

"With the qualification of TSMC's 0.18-micron process, our customers now have another reliable manufacturing option to increase the flexibility of their designs by embedding reprogrammability for critical functions of their SoC devices," said Tim Garverick, Adaptive Silicon's president and chief operating officer.

ARC Cores Inc. has licensed its configurable 32-bit processor technology and USB controller to RF Micro Devices, which will use them in a Bluetooth baseband controller. RF Micro said it will combine the RF3001 ARC-based baseband controller with its existing RF2968 transceiver to create a compact, ultralow-cost solution for Bluetooth-ready PCs, laptops and peripherals (www.arccores.com).
