Need help simulating an NCO core (Label is unrelated)

Hi Ed,

The simulation process you described is the right process, there is no matter on simulating the IP with the Verilog or with the VHDL, both should work.

You are also right that some IP modules are encrypted, only when the Modelsim version is supported by the Quartus version, these models can be decrypted.

When you use the Quartus Prime Pro 18.1 to generate the NCO IP, we suggest you use the Modelsim SE 10.4d or the ModelSim-Intel FPGA Edition for simulation.
