Hi,When I try to verify a demo design in DSP Builder, I am getting the following error: "Cannot run program "vsim":....The system cannot find the file specified". But I have set the path of vsim.exe in the "File\Set Path" of MATLAB window. I can open the Modelsim by typing the command vsim.exe from the directory where it is present through the command window. If I type vsim in the MATLAB window, it says "undefined variable or function". Can anyone please help regarding this? Thanks.
