A column line can be directly driven by the LEs, IOEs, or ESBs in that
column. Row IOEs can drive a column line on a device’s left or right edge.
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.
