Well I still use Mathcad 2001, as I missed 2001i and I am not willing to accept a softlock to a certain computer hardware as with Mathcad 11 and newer.
So Mathcad 2001 was shipped with a crippled "light" version of a simulation software "VisSim Comm LE", with some examples how to use Mathcad...
This would be against the business modell of MathSoft :-), because you want to use the "engine" of Mathcad without price, like a compiler.
Neither Mathcad, nor Matlab/Simulink provide such.
With Labview, its different: You might do so with the LabWindows/CVI product.
Maybe you should consider...
