1.3.1.2. Intel® Stratix® 10 DDR4 External Memory Interfaces IP Core
The ddr4_emif logic includes the Intel® Stratix® 10 External Memory Interfaces IP core. This IP core interfaces to the DDR4 external memory, with a 64-bit interface that runs at 933 MHz. Also, the IP core provides 2 GB of DDR4 SDRAM memory space. The EMIF Avalon-MM slave runs at 233 MHz clock.
The following table lists the configuration fields of the Intel® Stratix® 10 External Memory Interfaces IP core that are different from the Intel® Stratix® 10 GX FPGA Development Kit with DDR4 HILO preset settings:
Setting | Parameter | Value |
---|---|---|
Memory - Topology | DQ width | 16 |
DQ pins per DQS group | 8 | |
Number of DQS groups | 2 | |
Alert# pin placement | I/O Lane with DQS Group | |
DQS Group of ALERT# | 0 |
