Fast CONNECT Switch Matrix
The Fast CONNECT switch matrix connects signals to the
FB inputs, as shown in
sponding to user pin inputs) and all FB outputs drive the
Fast CONNECT matrix. Any of these (up to a FB fan-in limit
of 36) may be selected, through user programming, to drive
each FB with a uniform delay.

Function Block
Function Block
The Fast CONNECT switch matrix is capable of combining
multiple internal connections into a single wired-AND output
before driving the destination FB. This provides additional
logic capability and increases the effective logic fan-in of the
destination FB without any additional timing delay. This
capability is available for internal connections originating
from FB outputs only. It is automatically invoked by the
development software where applicable.
