With DIMM, I can get timing the parameter from datasheet or DDR4. Once an eye diagram is established, analysis tools such as mask test, histogram and automated eye measurements can be applied. DDRx batch-mode in the Hyperlynx need the timing model for controller. In the second step a RDA (Read with Auto-Precharge) is issued. Write leveling path timing (applicable for DDR2 and DDR3 SDRAM with UniPHY, and DDR3 and DDR4 SDRAM with Arria 10 EMIF IP. The 4Gb DDR4 D-die device is available in 96ball FBGAs(x16).
