1.4.1.2. External Memory Interfaces Intel® Arria® 10 FPGA IP
The ddr4_emif logic includes the External Memory Interfaces Intel® Arria® 10 FPGA IP. This IP core interfaces to the DDR4 external memory, with a 64-bit interface that runs at 1066.0 MHz. Also, the IP core provides 2 GB of DDR4 SDRAM memory space. The EMIF Avalon® -MM slave runs at 300 MHz.
The following table lists the External Memory Interfaces Intel® Arria® 10 FPGA IP parameters that are different from the Intel® Arria® 10 GX FPGA Development Kit with DDR4 HILO preset settings:
Setting | Parameter | Value |
---|---|---|
Memory - Topology | DQ width | 64 |
DQ pins per DQS group | 8 | |
Number of DQS groups | 8 | |
Alert# pin placement | I/O Lane with Address/Command Pins | |
Address/Command I/O lane of ALERT# | 3 | |
Pin index of ALERT# | 0 |
