Virtex7 400MHz IDELAYCLTRL_REF

Jump to solution

Looking at the latest Virtex-7 datasheet (DS182 v1.21) I see that Table 26 has added 400MHz as a usable reference clock frequency for the IDELAYCTRL.  Previously only 200MHz and 300MHz were supported.  Are there any special requirement with regards to Vivado tool version or anything else to allow the use of this faster clock?

 

Thanks

I think you need to use 2014.4, and you need to be using a -2 or -3 speedgrade part.
