WebWrite data eye training—Aligning the center of the DQ eye to the DQS edge for write operations. DDR Interface Designer Settings The following tables describe the settings for the 钛金系列 DDR block in the Interface Designer. The settings should match the DRAM device that you are using. Table 14: Base Tab Parameter Choices Notes Web† Write leveling calibration: In D DR3 mode, set DQS, DQ, and DM si gnals of each data byte to their common timing delay relative to DDR CLK, ADDR, and Controls. This calibration is associated with the DDR3 “fly-by” board topology, as describ ed by the JESD79-3E standard. These settings are not used in LPDDR2 mode.

WebDDR3 Write Leveling With DDR3 the memory signals can be allowed to driven to each bank of memory or DIMM on a fly-by basis. This allows for easier routing on the board and single termination. Below, you can see that the CMD/ADDR/CLK drive every memory device. Whereas, the DQ/DQM/DQS drive “each” memory device.
