Problem Title:
M1.4 CPLD: The OFFSET timing constraint does not force the fitter to use global clocks
Problem Description:
Urgency: Standard
General Description:
If you use an OFFSET timespec on a net, the fitter does not force that net
to be a global clock net automatically.
Solution 1:
A BUFG=CLK property must be manually provided on the clock pad of the net that
has the OFFSET timespec associated with it.
