Array Coordinates
During many place-and-route operations in the Actel Designer software tool, it is possible to set
constraints that require 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.
Table 2-3
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 cells and edge core cells. In addition, the
I/O coordinate system changes depending on the die/package combination. It is not listed in
The Designer ChipPlanner tool provides array coordinates of all I/O locations. I/O and cell coordinates
are used for placement constraints. However, I/O placement is easier by package pin assignment.
