vlog-7 "Failed to open design unit file in read mode" error during simulation for Agilex7 board

Hello once more @BoonBengT_Altera!

I don't have a design to share, but I have interesting news nonetheless.

I have tried making multiple changes to the design (and, in particular, to the confidential part of it), and all the changes I have tried seemed to resolve the error, so I cannot share a design replicating it.

For example, changing the name of the component from "channel_compensation" to "c_comp" solves the error.

I tried some other smaller changes, but most surprisingly, reverting to the original code after that did not throw the error.

This was for the second design that I mentioned. The original design which threw a similar error also worked after shortening both the component name and changing the directory to one with a shorter path.

My guess is that it did in fact have something to do with maximum path length. This does not really explain why one of the designs failed, then worked again after changing it and undoing the changes...

But in any case, I no longer have a problem when trying to simulate my designs.

My advice for anyone facing a similar problem: try shortening the path and the component name.

Thank you and excuse me for not being able to provide clearer information!

Regards,

Noah
