% MODSIMSIGGEN - Demonstrate Link for ModelSim using MATLAB to implement a

% MODSIMSIGGEN shows how MATLAB can be used to implement a VHDL

% component that is used to drive to input of a VHDL project in ModelSim.

% This demo uses an empty project that displays the output being

% generated by the MATLAB component. It opens a GUI that allows the user

% to specify a wave type, amplitude and frequency and creates a VHDL

% componet that outputs a signal with these characteristics. A project

% containing this component is then c
