Stratix and Stratix GX device MultiTrack interconnect resources are
described in
Direct link routing saves row routing resources while providing fast
communication paths between resource blocks. Direct link interconnects
allow an LAB, digital signal processing (DSP) block, or TriMatrix
memory block to drive data into the local interconnect of its left and right
neighbors. LABs, DSP blocks, and TriMatrix memory blocks can also use
direct link interconnects to drive data back into themselves for feedback.
The Quartus II software automatically uses these routing resources to
enhance design performance.
For more information about LE architecture and the MultiTrack
interconnect structure in Stratix and Stratix GX devices, see the Stratix
Device Family Data Sheet section of the Stratix Device Handbook, Volume 1
or the Stratix GX Device Family Data Sheet section of the Stratix GX Device
Handbook, Volume 1.
DirectDrive Technology
When using APEX II or APE 20K devices, you must place critical paths in
the same MegaLAB
should place critical paths in the same MegaLAB structure for optimal
performance. However, this restriction does not exist in Stratix and
Stratix GX devices because they do not contain MegaLAB structures.
With the new DirectDrive
the actual distance between the source and destination of a path is the
most important criteria for meeting timing performance. DirectDrive
technology ensures that the same routing resources are available to each
design block, regardless of its location in the device.
