MathWorks, Mentor Provide System Co-Simulation with Link for ModelSim

10/28/2003 - The MathWorks and Mentor Graphics (NASDAQ: MENT) announced the upcoming release of The MathWorks Link for ModelSim®, which provides a co-simulation interface between The MathWorks MATLAB® and Simulink® system-level design environments with ModelSim®, Mentor Graphics' high-performance, high-capacity HDL simulator. With Link for ModelSim, engineers can efficiently verify and co-simulate ModelSim RTL-level designs using MATLAB and Simulink. The interface eliminates the errors and time associated with manual methods by automating the verification process. The product has completed a successful beta test and is expected to ship in late November.

Cosimulation and software test benching of a Manchester Receiver. The software test bench is created using Simulink, the DSP Blockset, and the Communications Blockset. Manchester Receiver implemented in VHDL and simulated in ModelSim.

Link for ModelSim is the first product to integrate MathWorks products directly into a hardware verification flow. System engineers use MATLAB and Simulink to create behavioral models of hardware systems that serve as executable specifications for implementation. Link for ModelSim provides system-level verification, software test benching, component modeling, and analysis capabilities. As a result, engineers can easily verify the HDL implementation against its original specification in MATLAB or Simulink, and gain rapid insight into HDL implementation problems. Allowing users to incorporate HDL into system-level simulations dramatically reduces the need for manual verification, saving time and minimizing the potential for errors.

The MathWorks industry-leading system-level design tools are well suited to complement ModelSim," said Robert Hum, vice president and general manager, design verification and test division, Mentor Graphics. "The ability to co-simulate, test, and verify VHDL and Verilog from MATLAB and Simulink narrows the gap between system design and hardware implementation domains, and provides customers with an enhanced tool flow that is efficient and easy to use."

Link for ModelSim is fully compatible with FPGA-based DSP design flow products from Xilinx and Altera. Engineers can now use MATLAB, Simulink, and ModelSim together with these products to verify and test large-scale FPGA implementations of signal processing systems. This compatibility allows users to move through the design, implementation, and verification phases quickly to isolate and correct any design flaws early and easily.

"With Link for ModelSim, The MathWorks addresses one of the key productivity issues facing engineers designing signal processing hardware," said Ken Karnofsky, director of marketing, DSP and communications, The MathWorks. "By partnering with Mentor Graphics to deliver an integrated system-level verification flow, we have taken a major step in support of our focus on the rapidly expanding market for FPGAs as a platform for high-performance DSP, as well as the traditional ASIC/IC market."

Link for ModelSim is scheduled to be available in late November, with the U.S. list price starting at $2,000. For additional information, please visit The MathWorks Web site at
