CPLD: 9500/XL :Sourcing internal logic with a global buffer
Problem Description:
Urgency: standard
General Description:
What kind of logic can I drive with a BUFG?
Solution 1:
If you try to use a global buffer to drive logic the fitter will use a regular IBUF instead.
However if you are driving multiple clocks and some logic, it will use the BUFG
to drive the clocks and the IBUF (from the same pad) to drive the combinatorial
logic.
