Enclustra Mercury+ XU8 - 3.12 QSPI Flash Programming from an External SPI Master; 3.13 Enclustra Module Configuration Tool

2.15.2 Signal Description
Please refer to the Mercury+ XU8 SoC Module FPGA Pinout Excel Sheet [4] for detailed information on the
DDR4 SDRAM connections.
2.15.3 Termination
Warning!
No external termination is implemented for the data signals on the Mercury+ XU8 SoC module. There-
fore, it is strongly recommended to enable the on-die termination (ODT) feature of the DDR4 SDRAM
device.
2.15.4 Parameters
Please refer to the Mercury+ XU8 SoC module reference design [2] for DDR4 settings guidelines.
The DDR4 SDRAM parameters to be set in the Vivado project are presented in Table 25.
The values given in Table 25 are for reference only. Depending on the equipped memory device on the
Mercury+ XU8 SoC module and on the DDR4 SDRAM frequency, the configuration may be different to the
one in the reference design. Please refer to the memory device datasheet for details.
