MAX 9000 Programmable Logic Device Family Data Sheet
Macrocells
The MAX 9000 macrocell consists of three functional blocks: the product
terms, the product-term select matrix, and the programmable register.
The macrocell can be individually configured for both sequential and
combinatorial logic operation. See
Figure 3
.
Figure 3. MAX 9000 Macrocell & Local Array
Combinatorial logic is implemented in the local array, which provides
five product terms per macrocell. The product-term select matrix allocates
these product terms for use as either primary logic inputs (to the
XOR
gates) to implement combinatorial functions, or as secondary inputs
to the macrocell’s register clear, preset, clock, and clock enable control
functions. Two kinds of expander product terms (“expanders”) are
available to supplement macrocell logic resources:
OR
and
I
Shareable expanders, which are inverted product terms that are fed
back into the logic array
Parallel expanders, which are product terms borrowed from adjacent
macrocells
I
The MAX+PLUS II software automatically optimizes product-term
allocation according to the logic requirements of the design.
