I have a part that needs to be located close to the edge of the board. I have used this before (9.3) and with a few tweaks to the rules I could get the edge of board releated errors to go away. This does not happen in 9.4.
I am working on a new design that uses this same part. Using the same DRC settings I still get error reports that do not reflect the settings. Now when I load the original design into 9.4, I get these errors that weren't there in 9.3.
This has happened in the past with previous firmware updates. You would think in testing there would be a set of known scripts or test cases to verify that known issues don't reappear. Unless we're the testing / validation department
