WebGreetings, I have been looking in the user guide (link) for the setup and hold times for FDRE registers of Artix-7 and I think I don't see them explicitly defined anywhere. This may be a very silly question but..is it in there and I just can't find it? If it's not, is it defined somewhere else? Cheers! Programmable Logic, I/O and Packaging. Like.

Web16 Jun 2011 · I find SDC file doesn't have constraints for input/output setup/hold. Instead, it has constraints of input/output delay. I think the negative value of input delay represents setup time, while positive for hold time. Is the conception right? Or there's other better way to specify clock-data setup/hold timing.
