Notes -
CLK TO SYNC
(1) DDR memory sends DQ aligned to DQS strobe.
(2) The DQS Strobe is delayed by 90 degree using the dedicated DQS logic.
(3) DQ is now center aligned to DQS Strobe.
(4) PRMBDET is the Preamble detect signal generated using the DQSBUFB primitive. This is used to
(5) The first set of IO registers A and B, capture data on the positive edge and negative edge of DQS.
(6) IO register C transfers data so that both data are now aligned to negative edge of DQS.
(7) DDCLKPOL signal generated will determine if the CLK going into the synchronization registers need to
(8) The IO Synchronization registers capture data at on positive edge of the FPGA CLK.
