OK, so I started doing this, and got about half way through the list (there are 27 .sdc files total) without seeing any improvement. So I took the extreme approach and removed all of the .sdc files except:
- the project .sdc file
- the three (temporary? not sure how this works) .sdc files which appear for a while during build under the qdb folder
When I do this, the timing errors go away, but there are no timing checks at all for the clock domain which was causing the problem; in fact, approximately half of the clocks no longer appear in the clock report (with the .sdc files in, there are ~135 clocks; without the .sdc files, there are only about 62 clocks).
