100G Ethernet IP (Stratix 10) does not complete placement

Hi, We're attempting to route a 100G interface with RS-FEC, using the Low Latency 100G IP. When we configure the IP without RS-FEC, it routes, but when we enable RS-FEC, it consistently fails to s...

    Hi @JMiret

    Yup, it seems to be the case. In fact, I would recommend users to use the latest Quartus version 21.2 as we have fixed quite a few errors in the latest Quartus release.

    With that, I believe your current issue has been resolved. Do you need further help in regards to this case?

    Best Regards,

HI,


  1. May I know are you encountering Quartus fitter compilation error ? What's the error message ?
  2. Which S10 Ethernet 100G IP that you are using ? H-tile hard IP ? E-tile hard IP or low latency 100G soft IP ?
  3. If you are using Hard IP then you may want to review the channel placement design requirement as RS_FEC is only available in certain channel only. Pls check out the respective Ethernet IP user guide doc to find out more info


If you are able to share your Quartus design QAR file here then I can help to review your design channel placement as well.

  • Just remove all your own sensitive user logic design and left with Ethernet 100G IP connection that able to reproduce the fitter error will do


Thanks.
