ARRIA 10 with DDR4

Jump to solution

Hi ,

I am designing a board which include ARRIA 10 10AX022E4F27I3LG  and a single DDR4 device .

I am using the DDR4 with the highest speed bin  MT40A512M16LY-062E   (062E means 1600Mhz clock means 3200 MT/S).

but , I want to work with a 800Mhz clock not with 1600mhz clock. ( clock from the ARRIA 10 to the DDR4)

in the Quartus EMIF IP wizard in the MEM TIMING tab in the SPEED BIN the highest speed bin which is available is 2666 MT/S and not 3200 MT/S.

can i use the 3200 MT/S DDR4 device (operated with 800Mhz clock) although its speed bin is not available in the Quartus EMIF IP wizard  ?  

Thanks,

Lior

HI Lior,

 

Sorry for not getting your question right in the first place.

 

Yes, You can select 2666MT/S speed bin , but enter the timing values associated with 3200 MT/S referring to memory datasheet.

 


Please enter Parameters dependent on speed bin, operation frequency and page size associate with 800 MHZ values.

  

Hope this helps.
