I can't get any output value of FFT IP simulation with NCO IP input.

Hi, I'm trying to simulate with fft ip with nco ip input. But I can't get any value on waveform.

I just made project with nco ip, fft ip and top module.

I add each .qip files on project.

and open Altera-modelsim by RTL-Simulation on Quartus Prime Standard 17.1.

I created testbench and tried simulation but it occur errors, so I can't get any signal with value.

( one of the error is

'Error: (vsim-3033) E:/intelFPGA/working_directory/fft_ip/nco_gen/synthesis/submodules/nco_gen_nco_ii_0.v(332): Instantiation of 'asj_nco_isdr' failed. The design unit was not found.
# Time: 0 ps Iteration: 0 Instance: /fft_ip_tb/ufft/u0/nco_ii_0 File: E:/intelFPGA/working_directory/fft_ip/nco_gen/synthesis/submodules/nco_gen_nco_ii_0.v'

)

Is there things I have to do more?


When I did test with 1 ip, I changed directory to simulation/mentor and use msim_setup and ld_d command.

But now I'm using 2 ip, so I don't know how I can add submodules...

    Hi,


    Can you please first try by giving a constant input to FFT IP and once it worked then feed NCO IP output to the FFT IP.


    Also, You need make sure to add your testbench and dependent files in the script you are executing.


    Thank you

      I tried simulation with example of FFT IP.

      I just made example design using Platform Designer and I added fft.sip and fft.qip file to project.

      and I set fft_ii_0_example_design.v file to top module.

      -> compile is ok (in Compilation menu)

      I changed to RTL simulation and start but I failed simulation...
