The compiler can allocate up to three sets of up to five parallel expanders
automatically to the macrocells that require additional product terms.
Each set of five parallel expanders incurs a small, incremental timing
delay (t
Compiler uses the five dedicated product terms within the macrocell and
allocates two sets of parallel expanders; the first set includes five product
terms and the second set includes four product terms, increasing the total
delay by 2 × t
Two groups of 8 macrocells within each LAB (e.g., macrocells
1 through 8 and 9 through 16) form two chains to lend or borrow parallel
expanders. A macrocell borrows parallel expanders from lower-
numbered macrocells. For example, macrocell 8 can borrow parallel
expanders from macrocell 7, from macrocells 7 and 6, or from macrocells
7, 6, and 5. Within each group of 8, the lowest-numbered macrocell can
only lend parallel expanders and the highest-numbered macrocell can
only borrow them.
borrowed from a neighboring macrocell.

Unused product terms in a macrocell can be allocated to a neighboring macrocell.
