Quartus 18.0 generates a different RBF file for each compile. What setting is causing this behavior? Please see details section

I have attached a qar file that was archived with Quartus 18.0. When we restored this project and compiled, we got a different RBF file than the original SRM_VENTNOR.rbf file that is attached. Each t...

Hi,

Thanks for the design.

I checked with your design & observed that .rbf files generated from this project shows equivalent by KDiff3 Tool even this project consists of PLL IP. so as you mentioned in your very first post , there might be some issue with that design.

let me check with my team since issue is replicated & get back to you.

Regards,

Vicky

    Please double check the compiler settings between the two QAR files as well to ensure that it's not any compiler setting causing the issue. Thanks.

    Hi Vicky,

    I am the Intel PSG FAE at Arrow that supports this customer and I could replicate the issue also but could not explain why this issue was happening. I looked at the "good" design to check the settings and didn't see anything different from the "bad" design.

    Have you or your team had a chance to investigate why this one design from the customer gets different RBF files after each compile?

      Hi PFong2 & SZack,

      Could you please check again by creating the fresh deign with all the files included in that erroneous design?

      we are working on it & will let you know once we get any update.

      Thanks,

      Vicky

      Hi Vicky,

      We have two designs that use the similar core modules that do not exhibit this issue. Only the initial design (SRM_VENTNOR) that I sent you has this issue. It's been over two months since I submitted this inquiry. Could we escalate this issue so we can converge on a resolution sooner than later?

      Thanks,

      Phil
