Intel FFT simulation was failed in 2 Matlab version

Hello Sir/Madam,

Quartus prime pro 17.1 + Modelsim 10.5c +Arria10gx

Intel FFT IP core , Variable Streaming,N=256,data type is single.

I generated an Intel FFT ipcore from Quartus, I can see some Matlab <variation name>_model and <variation name>_tb files have been generated under my nominated location E:\gofft\tfft\altera_fft_ii_171\sim\Matlab_model\

Following the simulation instruction, 2.5.2. Simulating the Variable Streaming FFT IP Core in the MATLAB, on page 24 of ug_fft.pdf. I got something wrong as below

>> nps=[256,2048];

inverse = [0,1];

>> x = (2^12)*rand(1,sum(nps)) + j*(2^12)*rand(1,sum(nps));

>> [y] = tfft_altera_fft_ii_171_tp3vvyi_model(x,nps,inverse);

Invalid MEX-file

'\\client\e$\gofft\tfft\altera_fft_ii_171\sim\Matlab_model\SVSfftmodel.mexw64': Access is

denied.

Error in tfft_altera_fft_ii_171_tp3vvyi_model (line 47)

[roc,ioc] = SVSfftmodel(rin,iin,DATA_PREC,TWIDDLE_PREC,N,nps(i),inverse(i), INPUT_ORDER,

OUTPUT_ORDER,REPRESENTATION,SVOPT,PRUNE);

Because I have noticed some old answer for similar question mentioned this simulation only support 32bit Matlab. So I have tried this test on below 2 platform,

Both 2 platform,I got same error information .I have restart matlab and computer ,and issue still same.

Cast case 1 :Win10 + MatlabR2019b

Cast case 2 :Win7+ Matlab6.5.1

Any suggestion is welcome

Thanks

Jim
