How is important this? Thanks. --- Quote End --- Hi, it looks to me that you have a large clock skew, because your required P2P requirement is 14.645 ns. Please select one row in the result tab, right mouse clock, choose "List Path". Expand all "+" signs and post the result or attache it. Kind regards GPK
