Every time the super cluster allocator is used, there is an incremental delay of t
tor is used, all destinations other than the one being steered to, are given the value of ground (i.e., if the super clus-
ter is steered to M (n+4), then M (n) is ground).

Macrocell
The 16 macrocells in the GLB are driven by the 16 outputs from the logic allocator. Each macrocell contains a pro-
grammable XOR gate, a programmable register/latch, along with routing for the logic and control functions. Figure
5 shows a graphical representation of the macrocell. The macrocells feed the ORP and GRP. A direct input from
the I/O cell allows designers to use the macrocell to construct high-speed input registers. A programmable delay in
this path allows designers to choose between the fastest possible set-up time and zero hold time.

Enhanced Clock Multiplexer
The clock input to the

op can select any of the four block clocks along with the shared PT clock, and true and
complement forms of the optional individual term clock. An 8:1 multiplexer structure is used to select the clock. The
eight sources for the clock multiplexer are as follows:
