Urgency: Standard
Description
If you want to use FGM mode in a 3k design but don't want to
use a CLB primitive library symbol. FGM mode is used when there
is 'P' attribute on the E-pin of a CLB MAP
Solution 1:
(1) Use a CLBMAP in schematic.
(2) E-pin of the CLBMAP must be a net going to the
select line of a mux
(3) Place a 'P' attribute on the CLBMAP E-pin.
