Problem in Interfacing HBM2 with NIOS on Stratix10 MX board

[mounika]

Hi,

Iam trying to use HBM2 memory interface module that is integrated in Stratix10 MX board. It contained AXI slave port, but Nios or any other masters in Qsys are having Avalon interface.

As per the document of Qsys interconnect it says that Avalon and Axi can be interfaced directly. I tried the same but my functionality is not working.

Could you suggest me any method of interfacing this Avalon with AXI interface. Thanks in advance....

When you say "functionality is not working," can you elaborate? Were you able to successfully build a system design in Platform Designer or Quartus, compile it, etc.? What exactly is not working?

Yes, Iam able to build a system and compile it. But while checking Reads and writes with Nios iam not able to access the integer points. I performed writing into hbm and reading from hbm through Nios in Eclipse.
