Specifications
DQS pins are listed in the Cyclone IV pin tables as DQSXY, in which X indicates the
DQS grouping number and Y indicates whether the group is located on the top (T),
bottom (B), or right (R) side of the device. Similarly, the corresponding DQ pins are
marked as DQXY, in which the X denotes the DQ grouping number and Y denotes
whether the group is located on the top (T), bottom (B), or right (R) 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.
