    Hi there,

    I apologize for the late reply, due to Lunar New Year.

    Please try the following:

    1. You will need below INIs variable :

    • emif_restrict_hps_refclk_to_ac_tile=off

    1. Open the fitter_error.qar file, add the INI file with emif_restrict_hps_refclk_to_ac_tile = off.

    2. Then re-check the fitter.

    Could you please try using these INIs and let us now if the error disappears when placing an HPS-EMIF?

    2. If not, could you try using Quartus 19.1 if are you seeing the same error? Please let us know if the error the same when using Quartus 19.1.

    Regards.
