Constraining nets

[newkid_old]

I have an LVDS pair that I bring to a IBUFDS which then feeds my SelectIO module.  Implementation is report a timing hold error.  Does anyone know how to constrain this net to it corresponding data clock?  This particular module has a data clock that feeds it for deserialization and I would have thought Vivado would know to use that clock but based off of the error that's not true.

Hi @newkid_old,

Here is a forum thread that discusses using the Utility Buffer IP Core.

thank you,
