2015.1 Vivado UltraScale Partial Reconfiguration - Can the BUFG in the static region drives BUFG loads in the reconfigurable module

Description

In a Partial Reconfiguration design targeting an UltraScale device, can the BUFG in the static region drive BUFG loads (BUFGCE, BUFG_GT or BUFGCTRL) in the reconfigurable module?

Solution

This connection is now illegal.


From Vivado 2015.1, DRC HDPR59 is added to avoid this type of topological structure:

Rule violation (HDPR-59) Illegal clock load '<name>' found on PR boundary clock net '<name>'. Static clock nets are not allowed to drive loads inside of a reconfigurable region of type BUFGCE, BUFG_GT or BUFGCTRL. Remove the series buffer inside of the PR region to correct this issue.
