7. Dynamic Reconfiguration

Dynamic reconfiguration is the process of modifying transceiver channels to meet changing requirements during device operation. You can customize channels by triggering reconfiguration during device operation or after device configuration.

Dynamic reconfiguration is available for E-tile Transceiver Native PHY.

Note: The Embedded Multi-die Interconnect Bridge (EMIB) can also be reconfigured in addition to channels using the reconfiguration interface.

Use the reconfiguration interface to dynamically change the transceiver channel settings and EMIB settings for the following applications.

  • Fine tuning signal integrity by adjusting TX analog settings and RX adaptation settings
  • Enabling or disabling transceiver channel blocks, such as the PRBS generator and verifier, and loopback modes
  • Changing TX/RX settings for multi-data rate support protocols such as CPRI
  • Enabling/disabling RS-FEC

The Native PHY IP cores provide the following features that allow dynamic reconfiguration:

  • Reconfiguration interface
  • Configuration files
  • Multiple reconfiguration profiles
  • Embedded reconfiguration streamer
  • Native PHY Debug Master Endpoint (NPDME)
  • Optional reconfiguration logic

Also see Unsupported Features.

The RS-FEC Avalon® memory-mapped interface allows you to reconfigure the RS-FEC block and monitor status.
