Description
Due to a problem in the Intel® Quartus® Prime software version 14.1.a10s and earlier, you may see simplex instances of the Intel Arria® 10 Native PHY IP generating duplex dynamic reconfiguration files. For example, an RX-only variant will generate reconfiguration files that contain TX and RX data.
