Table 5. Product Term Expansion Capability
Every time the super cluster allocator is used, there is an incremental delay of tEXP. When the super cluster alloca-
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 ip-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:
