First question asked Welcome!

Hi

we see memory test failures when running memtest in an eternal loop, it happens about once a day, and once it was running a week without failures. So I wonder if anyone has run a long memory test on some FPGA board? What board? What IP was used? How long was the longest test run?

So far I see several reports that there are failures on running memory tests, from different people, different FPGA boards, and different IP cores.

I am currently using OpenHBMC:

https://github.com/OVGN/OpenHBMC

With this board:

https://shop.trenz-electronic.de/de/CR00107-01-CRUVI-carrier-board-with-AMD-Spartan-7

I do not think there is a signal integrity issue: all HyperBUS wires are between 2 and 4 mm in length. 

Thanks!

Hi @openchip ,

 

Could you please provide necessary inputs for following points?

 

>Please clarify which Hyper Ram you are using (Gn1/Gn2).

> Are you using IP simulation provided by Infineon? If yes, then from where you got this IP simulation?

>Could you please attach failure waveforms?

>No of affected devices?

 

Thanks,

Shubham
