3.19. 10GBASE-R PHY Dynamic Reconfiguration for Arria V and Stratix V Devices
For Arria V and Stratix V devices, each channel and each TX PLL have separate dynamic reconfiguration interfaces. The MegaWizard Plug-In Manager provides informational messages on the connectivity of these interfaces. The example below shows the messages for a single duplex channel.
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 Controllers. Doing so causes a Fitter error. For more information, refer to Transceiver Reconfiguration Controller to PHY IP Connectivity. Allowing the Intel® Quartus® Prime software to merge reconfiguration interfaces gives the Fitter more flexibility in placing transceiver channels.
Informational Messages for the Transceiver Reconfiguration Interface
Reconfiguration interface offset 0 is connected to the transceiver channel.
PHY IP will require 2 reconfiguration interfaces for connection to the external reconfiguration controller.
Reconfiguration interface offset 0 is connected to the transceiver channel.
Reconfiguration interface offset 1 is connected to the transmit PLL.
The following table describes the signals in the reconfiguration interface; this interface uses the Avalon-MM PHY Management interface clock.
Signal Name | Direction | Description |
---|---|---|
reconfig_to_xcvr [(<n>70-1):0] |
Input | Reconfiguration signals from the Transceiver Reconfiguration Controller. <n> grows linearly with the number of reconfiguration interfaces. This signal is only available in Stratix V devices. |
reconfig_from_xcvr [(<n>46-1):0] |
Output | Reconfiguration signals to the Transceiver Reconfiguration Controller. <n> grows linearly with the number of reconfiguration interfaces. This signal is only available in Stratix V devices. |
