XPM_FIFO_ASYNC simulation - xpm_fifo.sv : file does not exist

Jump to solution

I wrote a testbench to better understand the details of XPM_FIFO_ASYNC.

 

While stepping through my testbench, I get a strange warning that the file 'xpm_fifo.sv' does not exist. However, subsequent steps seem to 'walk through' this very same file :

Hi @ronnywebers,

 

This warning can be ignored as the simulator uses pre compiled version of xpm_fifo.sv. Hence you are able to walk through the file.

 

Thanks,
