Flip-Flops
The CLB can pass the combinatorial output(s) to the inter-
connect network, but can also store the combinatorial
results or other incoming data in one or two flip-flops, and
connect their outputs to the interconnect network as well.
The two edge-triggered D-type flip-flops have common
clock (K) and clock enable (EC) inputs. Either or both clock
inputs can also be permanently enabled. Storage element
functionality is described in
Table 2
.
Latches (XC4000X only)
The CLB storage elements can also be configured as
latches. The two latches have common clock (K) and clock
enable (EC) inputs. Storage element functionality is
described in
Table 2
.
Clock Input
Each flip-flop can be triggered on either the rising or falling
clock edge. The clock pin is shared by both storage ele-
ments. However, the clock is individually invertible for each
storage element. Any inverter placed on the clock input is
automatically absorbed into the CLB.
Clock Enable
The clock enable signal (EC) is active High. The EC pin is
shared by both storage elements. If left unconnected for
either, the clock enable for that storage element defaults to
the active state. EC is not invertible within the CLB.
