FastTrack Interconnect
In the FLEX 8000 architecture, connections between LEs and device I/O
pins are provided by the FastTrack Interconnect, a series of continuous
horizontal (row) and vertical (column) routing channels that traverse the
entire FLEX 8000 device. This device-wide routing structure provides
predictable performance even in complex designs. In contrast, the
segmented routing structure in FPGAs requires switch matrices to
connect a variable number of routing paths, which increases the delays
between logic resources and reduces performance.
The LABs within FLEX 8000 devices are arranged into a matrix of
columns and rows. Each row of LABs has a dedicated row interconnect
that routes signals both into and out of the LABs in the row. The row
interconnect can then drive I/O pins or feed other LABs in the device.
