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.
