I've created a packaged IP for a 4bit adder (Vivado 2018.3). Mostly an exercise in learning to make sure I know what I'm doing when I start packaging up truly needed IP's.
The packaging of the IP from the project went fine, no issues.
Using the newly created IP in a new project works fine with an exception; During the implementation run 27 critical errors pop up. Each of these errors point to an uncommented line in the constraint file. However, once the implementation is done I then build the bitstream, program the board (Basys3) and....**POOF** everything is working fine. So the 27 critical errors don't cause a 'show stopper'.
I'd like to figure out WHAT is causing these errors so I can resolve the problem and not have this issue propagated thru the IP's I create for use in other projects.
See the attached image.
Any hints, guidance, suggestions (or answers) would be greatly appreciated.
