You may observe the below info message (15134) during Fitter compilation in Intel® Quartus® Prime Pro software version 18.0 for Intel® Arria® 10 devices if you are using XCVR_RECONFIG_GROUP assignment to merge two transceiver reconfiguration interfaces. This information message reminds the user to check the transceiver pin locations if a fitter error occurs.
Info (15134): You specified location assignments for transceiver Avalon Memory-Mapped interface group"0". If the Fitter reports placement errors for the merged transceiver Avalon Memory-Mapped interface, check whether the two locations map to the same physical transceiver channel.
There is no workaround required.
This information message can be safely ignored if there is no fitter compilation error. No further action is required.
