CPLD: 9500/XL :Sourcing internal logic with a global buffer


Urgency: standard

General Description:

What kind of logic can I drive with a BUFG?


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
