Honored ContributorDDR4 connection to Arria10
Hi.
How to connect the pins of the DDR4(1200 MHz) chip to the Arria10 chip? How to determine where to connect? For example I want to use a 3A Bank and a 512x8 DDR4 chip or a 3A and 3B banks and a 253x16 DDR4 chip. In Bank 3A(512x8 DDR4): W9 - VREFCA AA13 - RZQ resistor 240 Om AD3, AC3 - input refclk dif pair 300MHz AE2, AD2 - DQS dif pair AC1, AC2 - output for clk pair DDR4 chip AE1, AF2, AG1, AF1, AG3, AF3, AH2, AH3 - DQ[7:0] And the rest of the signals to connect to any free contacts, isn't it? Are the contacts used in the Bank 3B the same way?1 Reply
Altera_ForumTake a look at the Read Me file generated along with the IP. It's buried a little in the file structure, put it gives examples for pin selections. You can also use Interface Planner (Blueprint) if you are using the Pro edition. Check out this online training and its follow-ons for details:
