'hdlv_copyfiles' used in an example doesn't work, and nothing comes up for that when I google. Is there a typo?

I am trying to follow the instructions here in my local MATLAB: https://www.mathworks.com/help/hdlverifier/examples/generate_uvm_test_bench_from_simulink.html

However I am getting this error from the very first line in the example:

hdlv_copyfiles('hdlv_uvmtb', 'my_dir', '.')
Undefined function or variable 'hdlv_copyfiles'.

Is there a 'hdlv_copyfiles' command? I'm suspicious because googling give me absolutely nothing, which is strange. Does anyone know where the documentation is for this command is or what MATLAB functionality is required for it?

I tried this example, and was able to run it fine: https://www.mathworks.com/help/dsp/examples/generate-hdl-code-for-high-throughput-channelizer.html

I checked and I have the required tools (Simulink Coder, HDL Verifier, DSP System Toolbox). There is a folder named 'my_dir' at the level where I am running the command.

I think it is an example helper file. If the HDLVerifier is installed correctly the file should be at this location

matlab/toolbox/hdlverifier/hdlverifier_examples

[Walter Roberson]

I suspect that the user is using a release from before that function existed. I do not have that toolbox myself so I cannot check older versions.

Thank you for the information. I have R2019a but followed my corporate instructions for installation which may have been non-typical.

I was able to get my MATLAB root folder by typing 'matlabroot' into MATLAB command line, then was able to go to toolbox/hdlverifier/hdlverifier_examples from there.

However the commands

>> model = 'hdlv_uvmtb';
>> open_system(model);

Still gives:

No system or file called 'hdlv_uvmtb' found.

I looked and there wasn't a file called hdlv_uvmtb anywhere I could see. Is there somewhere online I can get the files? This functionality would be very helpful for us so I'd really like to get it working.

The https link is to our latest documentation which is for R2019b. Your local installation doc should match R2019a and will not have this example.

(The example did not exist in R2019a.)

[John Smith]

I understand. Is it possible to download the example from somewhere?

[Walter Roberson]

Yes, the easiest way to download the example is to download and install r2019b.

(or if you wait another few weeks then history suggests that R2020a will be released before the equinox)
