The DQS pins are listed in the Cyclone III pin tables as DQSXY, where X
indicates the DQS grouping number and Y indicates which side of the I/O
bank the DQS pins belong. The Y can be T for pins on the top, B for pins
on the bottom, L for pins on the left, or R for pins on the right side of the
device. Similarly, the corresponding DQ pins are marked as DQXY, where
the X denotes which DQ group the pins belong to and Y denotes the I/O
bank location of the DQ pins. The Y can be T for pins on the top, B for pins
on the bottom, L for pins on the left, or R for pins on the right side of the
device. For example, DQS2T indicates a DQS pin belonging to group 2,
located on the top side of the device. Similarly, the DQ pins belonging to
that group is shown as DQ2T.
