A row line can be driven directly by LEs, IOEs, or ESBs in that row.
Further, a column line can drive a row line, allowing an LE, IOE, or ESB to
drive elements in a different row via the column and row interconnect.
The row interconnect drives the MegaLAB interconnect to drive LEs,
IOEs, or ESBs in a particular MegaLAB structure.
A column line can be directly driven by LEs, IOEs, or ESBs in that column.
A column line on a device’s left or right edge can also be driven by row
IOEs. The column line is used to route signals from one row to another. A
column line can drive a row line; it can also drive the MegaLAB
interconnect directly, allowing faster connections between rows.
