All embedded blocks communicate with the logic array similar to LAB-
to-LAB interfaces. Each block (i.e., M4K memory or PLL) connects to row
and column interconnects and has local interconnect regions driven by
row and column interconnects. These blocks also have direct link
interconnects for fast connections to and from a neighboring LAB.
