Routing Structure
The MX architecture uses vertical and horizontal routing tracks to interconnect the various logic and I/O
modules. These routing tracks are metal interconnects that may be continuous or split into segments.
Varying segment lengths allow the interconnect of over 90% of design tracks to occur with only two
antifuse connections. Segments can be joined together at the ends using antifuses to increase their
lengths up to the full length of the track. All interconnects can be accomplished with a maximum of four
antifuses.
Horizontal Routing
Horizontal routing tracks span the whole row length or are divided into multiple segments and are located
in between the rows of modules. Any segment that spans more than one-third of the row length is
considered a long horizontal segment. A typical channel is shown in Figure 1-6. Within horizontal routing,
dedicated routing tracks are used for global clock networks and for power and ground tie-off tracks. Non-
dedicated tracks are used for signal nets.
Vertical Routing
Another set of routing tracks run vertically through the module. There are three types of vertical tracks:
input, output, and long. Long tracks span the column length of the module, and can be divided into
multiple segments. Each segment in an input track is dedicated to the input of a particular module; each
segment in an output track is dedicated to the output of a particular module. Long segments are
