17.31. Sharing Reconfiguration Interface for Multi-Channel Transceiver Designs

Although you must initially create a separate reconfiguration interface for each channel and TX PLL in your design, when the Intel® Quartus® Prime software compiles your design, it reduces the number of reconfiguration interfaces by merging reconfiguration interfaces. The synthesized design typically includes a reconfiguration interface for at least three channels because three channels share an Avalon-MM slave interface which connects to the Transceiver Reconfiguration Controller IP Core. Conversely, you cannot connect the three channels that share an Avalon-MM interface to different Transceiver Reconfiguration Controller IP Cores. Doing so causes a Fitter error.
