SuperSim™ Model simulates 0.3 Million Instructions Per Second

ORLANDO, FLORIDA, DSP World Fall Design Conference, November 1, 1999 -- AXYS Design Automation, Inc., of Irvine, California announced today at the ICSPAT'99/DSP World Expo in Orlando, Florida, the immediate availability of the phase-accurate SuperSim HW/SW co-verification model for the OakDSPCoreÒ from DSP Group. The new model offers a 1000x speedup over the OakDSPCore RTL model, with full phase-level accuracy and complete software debugging support. The model was successfully verified against DSP Group's HW reference model on the accompanying test suites.

"Licensees of DSP Group's OakDSPCore are now able to run CDMA and GSM software and HW/SW co-simulations in minutes instead of days with the full confidence that they are getting the same results as with the RTL model," says AXYS' President Vojin Zivojnovic.

OakDSPCore is a 16-bit general purpose low-power, low-voltage and high speed licensable Digital Signal Processing (DSP) core designed for speech/audio processing, telecommunications, digital cellular, and embedded control applications. Among the applications supported by OakDSPCore are cellular telephones, facsimile machines, modems and hard disk drives. In combination with the ARM7TDMI core, OakDSPCore represents a main component in advanced System-on-a-Chip solutions for portable wireless devices.

"Through the cooperation with AXYS, our SmartCoresÒ licensees now have the ability to make HW/SW trade-offs and verify their System-on-a-Chip designs early on in the design cycle," said DSP Group's Director of Development Tools & SW Support, Eyal Ben-Avraham.

The new model is currently available with the SW debugger, VHDL and Verilog wrappers, as well as part of the co-verification tools of Cadence, Mentor and Yokogawa scheduled for Q4'99. The models for other cores of DSP Group, including the TeakLite™ DSP Core, the TeakDSPCoreÒ and the PalmDSPCoreÒ will follow shortly.
