Array Coordinates
During many place-and-route operations in the Actel
Designer software tool, it is possible to set constraints
that require array coordinates.
reference. The array coordinates are measured from the
lower left (0, 0). They can be used in region constraints
for specific logic groups/blocks, designated by a wildcard,
and can contain core cells, memories, and I/Os.

memory blocks.
I/O and cell coordinates are used for placement
constraints. Two coordinate systems are needed because
there is not a one-to-one correspondence between I/O

Note: The vertical I/O tile coordinates are not shown. West side coordinates are {(0, 2) to (2, 2)} to {(0, 77) to (2, 77)}; east side coordinates
