MultiTrack Interconnect
2–24
Stratix II Device Handbook, Volume 1
R24 row interconnects span 24 LABs and provide the fastest resource for
long row connections between LABs, TriMatrix memory, DSP blocks, and
Row IOEs. The R24 row interconnects can cross M-RAM blocks. R24 row
interconnects drive to other row or column interconnects at every fourth
LAB and do not drive directly to LAB local interconnects. R24 row
interconnects drive LAB local interconnects via R4 and C4 interconnects.
R24 interconnects can drive R24, R4, C16, and C4 interconnects.
The column interconnect operates similarly to the row interconnect and
vertically routes signals to and from LABs, TriMatrix memory, DSP
blocks, and IOEs. Each column of LABs is served by a dedicated column
interconnect. These column resources include:

Stratix II devices include an enhanced interconnect structure in LABs for
routing shared arithmetic chains and carry chains for efficient arithmetic
functions. The register chain connection allows the register output of one
ALM to connect directly to the register input of the next ALM in the LAB
for fast shift registers. These ALM to ALM connections bypass the local
interconnect. The Quartus II Compiler automatically takes advantage of
these resources to improve utilization and performance.
