Figure 16. FastLUT Interconnect

ESB rows also have their own interconnect resources to communicate

horizontally and vertically with LAB rows. The ESB rows at the top and

bottom of the device have their own set of row and priority row

interconnect resources. For vertical communication, all LAB column

interconnect lines traverse to the ESBs. This includes leap lines, which

allow the adjacent LAB rows to communicate with the ESBs.

The row interconnect resources can be driven directly by LEs or ESBs in

that row. Further, the column interconnect resources can drive a row line,

allowing LEs, IOEs, and ESBs to drive elements in a different row via the

column and row resources.

The column interconnect resources can be directly driven by LEs, IOEs, or

ESBs within that column. The priority column and leap line resources can

be driven directly by LEs. These lines enable high-speed vertical

communication in the device for timing-critical paths. The column

resources route signals between rows. A column resource can drive row

resources directly, allowing fast connections between rows.
