csn not latching in IOB about hyperram HOT 2 OPEN

This is strange. I've just added your BUFR fix to this repo (copied from the MEGA65 fork) and rebuilt. The design works fine (as others already have reported).

However, I see no problems with the CSN register, see the following screen shots:


The CSN register is correctly placed in the IOB.

The line you added should not make a difference. I tried both with and without that line, and there is no change in behavior for me. Both with and without the design builds without any warnings related to IOB.

Are you sure your source code matches mine? I'm testing with commit 7068c29 in this repo. Are you able to share your toplevel code and constraints, perhaps in e-mail?

strange, on my PC it makes a difference, double checked the flow. I used the files from mega65 repo, not from here. But I think adding my added line is SAFE so why not add it?
