2014.2 Vivado Implementation - Logic Opt not auto-inserting BUFGs on unbuffered cmt CLKOUTx outputs

Description

When the user does not explicitly instantiate a BUFG on cmt CLKOUTx outputs, the expectation is that Logic Opt will insert a BUFG.

This does not happen in Vivado Design Suite 2014.2.

Solution

This will be corrected in the 2014.3 release so that BUFGs are automatically inserted.

Until then the work around is to instantiate the BUFG.
