7.2.3.3. Memory Parameters for QDR II and QDR II+ SRAM Controller with UniPHY Intel FPGA IP
Use the Memory Parameters tab to apply the memory parameters from your memory manufacturer’s data sheet.
Parameter |
Description |
---|---|
Address width |
The width of the address bus on the memory device. |
Data width |
The width of the data bus on the memory device. |
Data-mask width |
The width of the data-mask on the memory device, |
CQ width |
The width of the CQ (read strobe) bus on the memory device. |
K width |
The width of the K (write strobe) bus on the memory device. |
Burst length |
The burst length supported by the memory device. For more information, refer to memory vendor data sheet. |
Topology |
|
x36 emulated mode |
Emulates a larger memory-width interface using smaller memory-width interfaces on the FPGA. Turn on this option when the target FPGA do not support x36 DQ/DQS group. This option allows two x18 DQ/DQS groups to emulate 1 x36 read data group. |
Emulated write groups |
Number of write groups to use to form the x36 memory interface on the FPGA. Select 2 to use 2 x18 DQ/DQS group to form x36 write data group. Select 4 to use 4 x9 DQ/DQS group to form x36 write data group. |
Device width |
Specifies the number of memory devices used for width expansion. |
