The FastTrack interconnect consists of row and column interconnect
channels that span the entire device. The row interconnect routes signals
throughout a row of MegaLAB structures; the column interconnect routes
signals throughout a column of MegaLAB structures. When using the row
and column interconnect, an LE, IOE, or ESB can drive any other LE, IOE,
or ESB in a device. See
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.
