MAX 7000A Programmable Logic Device Data Sheet

Parallel Expanders

Parallel expanders are unused product terms that can be allocated to a

neighboring macrocell to implement fast, complex logic functions.

Parallel expanders allow up to 20 product terms to directly feed the

macrocell OR logic, with five product terms provided by the macrocell and

15 parallel expanders provided by neighboring macrocells in the LAB.

The compiler can allocate up to three sets of up to five parallel expanders

to the macrocells that require additional product terms. Each set of five

parallel expanders incurs a small, incremental timing delay (tPEXP). For

example, if a macrocell requires 14 product terms, the 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

× tPEXP.

Two groups of eight 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 eight, the lowest-numbered macrocell

can only lend parallel expanders, and the highest-numbered macrocell

can only borrow them. Figure 4 shows how parallel expanders can be

borrowed from a neighboring macrocell.
