Audio Embed Design in SDI Encounters Simulation Error With MIF

When simulating designs using Audio Embed IP, you will encounter the following errors or similar:

Error: 662 | # ** Warning: (vsim-3534) [FOFIR] - Failed to open file "db/top_audio_embed_0.ram0_audio_embed_sine_ram_b0d5e012.hdl.mif" for reading.Error: 663 | # No such file or directory. (errno = ENOENT) :

These errors indicate that the simulator cannot locate the .mif.

This issue affects all designs using the SDI MegaCore function version 13.0 SP1 and earlier.

To work around this problem, do one of the following steps:

Simulate your design using post-fitter simulation, where the simulation model file (.vo or .vho) can be generated through the EDA netlist writer.

Alternatively, you can run a synthesis on the over all design, and the missing .mif will now be generated in the db folder.

This issue will be fixed in a future release.
