Signaltap problem with Stratix 10 Production Kit

First, did you enable Signal Tap (the .stp file) for the design? Check the Signal Tap category in the project settings to make sure you enabled it (and recompile once enabled). If you created the file and then didn't enable it, it won't work. Are you manually adding an instance of Signal Tap to your HDL code or simply using the .stp file (preferred method)? The warning you see is not the issue. You don't normally need to add timing constraints for the JTAG interface or Signal Tap. Remove those constraints you added.

As for the SmartVID errors, I don't believe the S10 on the dev kit is set up for SmartVID. So perhaps your project is targeting the wrong device. My H-tile board projects target 1SG280HU2F50E2VGS1 (replace H with L for an L-tile, I think).

The easiest way to make sure you set up a project correctly for a dev kit is to either use a downloaded example project for the board or choose the Board tab when you're going through the New Project Wizard.
