WebExpert Answer. If you have HDL Verifier, you can cosimulate your design with Simulink using either Cadence Incisive or Mentor Graphics ModelSim. You will of course need one or the other of the HDL simulators. The high-level overview is that you create a HDL cosimulation block in Simulink that has the same interface as your top-level Verilog code. WebAfter that, the results of THD and the fundamental value corresponding to current and voltage are listed for generating mode. In the latter stage of simulation, the harmonic generation data of DFIM, extracted from the results of FFT analysis in MATLAB/Simulink, is used for the harmonic analysis toolbar of DIgSILENT PowerFactory.
