Figure 9. APEX 20K Interconnect Structure

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.

Figure 10 shows how the FastTrack Interconnect uses the local

interconnect to drive LEs within MegaLAB structures.
