Rules to Combine Groups
In 780-, 1152-, and some 1517-pin package devices, there is at most one ×16/×18 group
per I/O sub-bank. You can combine two ×16/×18 groups from a single side of the
device for a ×36 interface.
For devices that do not have four ×16/×18 groups in a single side of the device to
form two ×36 groups for read and write data, you can form one ×36 group on one side
of the device and another ×36 group on the other side of the device.
For vertical migration with the ×36 emulation implementation, check if migration is
possible by enabling device migration in the Quartus II project. The Quartus II
software supports the use of four ×8/×9 DQ groups for write data pins and migration
of these groups across device density.
two ×16/×18 DQS/DQ groups to form a ×32/×36 group on Stratix IV devices lacking
a native ×32/×36 DQS/DQ group.
