Hi Stefan,

The problem of this warning ID because the configuration pins are powered by different Vccio in different banks.

Solution: Enforce a configuration voltage level in the Configuration tab

Cheers

    Hello Shafiq,

    Pin-planner signal list shows vccio1b=1.8 and vccio8=3.3 because I defined these io-standards on their signals in assignment-editor.

    assignments > device > device and pin options > configuration : in this screen I tried with box checked/unchecked "Force Vccio to be compatible with configuration IO-voltage: but this gives no difference .... I don't see anything else I that relates to Vccio 0 config pins ? ?

    Regards,

    Stefan

      Hi Stefan,

      The issue is the configuration pins are powered by different Vccio.

      Have you tried use the same voltage for I/O bank 1B and I/O bank 8? If yes, is it able to solve the issue?

      Thanks

      ​Hello shafiq, PCB-layout is ongoing and I need to be sure that Vccio-1b and Vccio-8 do NOT need to be the same volage. Why should banks 1b and 8 need to have the same voltage as they have different Vccio-pins ? Vccio-1b = 1.8V because jtag pins are wired to a 1.8V powered device. Vccio-8 = 3.3V because bank8 pins are wired to 3.3V devices Changing this will impact my design and pcb-layout. Either can you confirm that Vccio-1b and Vccio-8 are allowed to be different voltage ? Or tell me how to suppress this warning ID=169202 ? Regards, Stefan

      Hi Stefan,

      I'm apologize to take so much time to get the confirmation regarding to this issue. I tested on my side and get the further confirmation from my colleague.

      The rule of thumb: The VCCIO for bank 1B (bank 1 for 10M02 devices) and bank 8 must be powered up to a voltage between 1.5V – 3.3V during configuration.

      Thus, as long as your Bank 1B & Bank 8 is powered up between that range, you are allowed to have different voltage or same voltage.

      When I did the duplication on my side, I also got the same warning as yours:

      Actually the warning that you get[Warning (169202)], is the false warning from Quartus. Quartus software Team will fixed it this false warning in future Quartus release.

      You may refer to this KDB:

      I'm apologize for inconvenience.

      Thanks
