Figure 8–12. Simplified Diagram of the DQS Phase Shift Circuitry
Notes to
(1) All features of the DQS phase-shift circuitry are accessible from the ALTMEMPHY megafunction in the Quartus II software.
(2) The input reference clock for the DQS phase-shift circuitry can come from a PLL output clock or an input clock pin. For the exact PLL and input
(3) Phase offset settings can only go to the DQS logic blocks.
(4) DQS delay settings can go to the logic array, the DQS logic block, and the leveling circuitry.

DLL
The phase offset control block ‘A’ is designated as
DLLOFFSETCTRL_<coordinate x>_<coordinate y>_N1 and phase offset
control block ‘B’ is designated as
DLLOFFSETCTRL_<coordinate x>_<coordinate y>_N2 in the Quartus II
assignment.
You can reset the DLL from either the logic array or a user I/O pin. Each time the DLL
is reset, you must wait for 1280 clock cycles before you can capture the data properly.
Depending on the DLL frequency mode, the DLL can shift the incoming DQS signals
by 0°, 22.5°, 30°, 36°, 45°, 60°, 67.5°, 72°, 90°, 108°, 120°, 135°, 144°, or 180°. The shifted
DQS signal is then used as the clock for the DQ IOE input registers.
All DQS and CQn pins referenced to the same DLL can have their input signal phase
shifted by a different degree amount but all must be referenced at one particular
frequency. For example, you can have a 90° phase shift on DQS1T and a 60° phase shift
on DQS2T referenced from a 200-MHz clock. Not all phase-shift combinations are
supported, however. The phase shifts on the DQS pins referenced by the same DLL
must all be a multiple of 22.5° (up to 90°), a multiple of 30° (up to 120°), a multiple
of 36° (up to 144°), or a multiple of 45° (up to 180°).
There are seven different frequency modes for the Stratix III DLL, as listed in
Table
frequency modes 0, 1, 2, and 3, the 6-bit DQS delay settings vary with PVT to
implement the phase-shift delay. In frequency modes 4, 5, 6, and 7, only 5 bits of the
DQS delay settings vary with PVT to implement a phase-shift delay; the most
significant bit of the DQS delay setting is set to 0.
