Vertical and Horizontal Routing

Vertical and Horizontal Tracks provide both local and long distance routing (Figure 2-37 on page 2-62).

These tracks are composed of both short-distance, segmented routing and across-chip routing tracks

(segmented at core tile boundaries). The short-distance, segmented routing resources can be

concatenated through antifuse connections to build longer routing tracks.

These short-distance routing tracks can be used within and between SuperClusters or between modules

of non-adjacent SuperClusters. They can be connected to the Output Tracks and to any logic module

input (R-cell, C-cell, Buffer, and TX module).

The across-chip horizontal and vertical routing provides long-distance routing resources. These

resources interface with the rest of the routing structures through the RX and TX modules (Figure 2-37).

The RX module is used to drive signals from the across-chip horizontal and vertical routing to the Output

Tracks within the SuperCluster. The TX module is used to drive vertical and horizontal across-chip

routing from either short-distance horizontal tracks or from Output Tracks. The TX module can also be

used to drive signals from vertical across-chip tracks to horizontal across-chip tracks and vice versa.
