The MathWorks and Mentor Graphics announce the 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' HDL simulator. With Link for ModelSim, engineers can 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. Link for ModelSim integrates MathWorks products directly into a hardware verification flow. Link for ModelSim provides system-level verification, software test benching, component modeling, and analysis capabilities. As a result, engineers can verify the HDL implementation against its original specification in MATLAB or Simulink, and gain insight into HDL implementation problems. Link for ModelSim is compatible with FPGA-based DSP design flow products from Xilinx and Altera. Engineers can use MATLAB, Simulink, and ModelSim together with these products to verify and test large-scale FPGA implementations of signal processing systems.
