New ContributorNCO simulation
I’m using Quartus lite edition and Intel Questa to develop my application. My application uses the NCO IP and I’m able to compile the design correctly but I’m not getting the NCO outputs toggling in the RTL simulation using Intel Questa. The Sin, Cos and the valid outputs are all in the U state although I’m not getting errors or warnings in Intel Questa. I wrote a simple design, a wrapper code (attached) to simplify the design and simulate the NCO IP and still the Sin, Cos and the valid outputs are all in the U state using Intel Questa RTL simulation. What could be the cause and how to simulate the NCO IP using Intel Questa? Please note that the .qip and the .sip files are added to the project.
Since you are using the Quartus Lite version, have you tried using the Nativelink simulation flow?
The Nativelink feature automatically compile your design, Intel IP, simulation model libraries and testbench.
