MIssing unisim libraries in ModelSIM

[ajasan]

Hi,

I'm trying to run a simulation in ModelSIM 10.1b from Vivado.

I have run the following command to add unisim libraries to sim environments

compile_simlib -simualtor modelsim

Even after that, while running simulation I get the "unisim.vcomponets not found"error.

Is there any other commands/libraries to be added.

Thanks,

Hi Asan,

Are you able to see unisim folder in the compiled library location?

If yes, follow below steps:

1. After modelsim gui invokes, click on the library tab

2. Navigate and select unisim in the libaries list

3. Right-click and select refresh

4. Run the .do file again,

Thanks,

Vinay

I did the same and the issue is not resolved.

it shows unisim library like this:

unisim(empty)

Does this give any clue?

Hi,

Can you attach your compile_simlib.log file?

Thanks,

Deepika.

[ajasan]

Please let me know where to find the log file. I searched in the vivado project folder. couldn't find

[vemulad]

Hi,

From where did you run compile_simlib command?

Run pwd command to know the present working directory. The log file will be seen at the same location.

Thanks,

Deepika.

[ajasan]

Thanks Deepika. Please find the log file attached

[vijayak]

BEGIN_COMPILATION_MESSAGES(modelsim:vhdl:unisim)
** Error: (vcom-7) Failed to open -f file "D:\Asan" in read mode.

No such file or directory. (errno = ENOENT)

Do you have access to the directory?

[vuppala]

Hi,

Try compiling the libraries again by removing the space in the directory path.

Thanks,

Vinay

Hi,

Setting compile_simlib main output directory to 'D:\Asan Jasima\IndoAust\Sim\CellOS_V1.0_Apr11\CellOS_XC7Z030.cache\compile_simlib'.

Use compile_simlib -directory to specify the location where the compiled libraries have to be stored.

The current output location had spaces in it so please specify a different location.

Thanks,

Deepika.

[ajasan]

Deepika's response gave me a clue.i.e, access to this folder "D:/Asan"?

A folder's name contained a "space" inbetween and it delimited the path with that. and hence searching in the wrong path.

Now I replaced space with dot and it worked.

Thank you all for your responses.

Great. Please close the thread by marking the answer.

Thanks,

Deepika.

Thanks for giving an example of the invocation of the compile_simlib command.  I tried this command several times based on what I found in UG900 and got an error regarding an unknown simulator.   I never did find the document that mentioned the need for the -simulator modelsim option.  I figured Vivado would take this information from the project settings.

Hello @emcalnan

Vivado takes the -simulator_exec_path from project settings but -simulator needs to be specified manually.

Thanks,
Vinay
