WebThe PHY_CALC spreadsheet calculates initial values that are needed by the leveling logic in the DDR3 PHY. You need to populate the lengths of the clock pair and the DQS pair to each SDRAM into this spreadsheet. This information is taken from the length matching report. WebThe standard speed which the BIOS will detect from reading the memory module is 1333. In the example below, the Serial Presence Detect (SPD) programmed speed is 1333. In automatic selection mode the BIOS …

Web1) The DDR3 PHY Calc spreadsheet is applicable to all KeyStone I devices. Some of these devices, for example the C6678, support a x64bit wide bus which has eight byte lanes. You can leave the length of the unused byte lanes as zero. 2) Microstrip refers to traces that are routed on the top or the bottom of the board. WebDDR4 Bandwidth Calculation Formula For DDR3 with Phy to memory controller interface clock ratio 2:1, bandwidth calculation goes as (bus_clock_frequency) * (bus_interface_width) * (2) / 8 (Bps) Is the same formula followed for Xilinx DDR4 bandwidth calculation where Phy to memory controller interface clock ratio is 4:1?
