The C4 interconnects span four LABs or M4K blocks up or down from a

source LAB. Every LAB has its own set of C4 interconnects to drive either

up or down. Figure 11 shows the C4 interconnect connections from an

LAB in a column. The C4 interconnects can drive and be driven by all

types of architecture blocks, including PLLs, M4K memory blocks, and

column and row IOEs. For LAB interconnection, a primary LAB or its LAB

neighbor can drive a given C4 interconnect. C4 interconnects can drive

each other to extend their range as well as drive row interconnects for

column-to-column connections.
