2.6.2. Dynamic Transceiver Reconfiguration Controller

RapidIO IP core variations that target an Intel® Arria® 10 and Intel® Cyclone® 10 GX devices include a reconfiguration controller block and do not require an external reconfiguration controller. All other RapidIO IP core variations require an external reconfiguration controller to function correctly in hardware.

For Arria II GX, Arria II GZ, Cyclone IV GX, and Stratix IV GX designs with high-speed transceivers, you must add a dynamic reconfiguration block (altgx_reconfig) to your design. You must connect it as specified in device handbook.This block supports offset cancellation. The design compiles without the altgx_reconfig block, but it cannot function correctly in hardware.

For Arria® V, Cyclone® V, and Stratix® V designs, you must add a dynamic reconfiguration block (Transceiver Reconfiguration Controller) to your design, and connect it to the RapidIO IP core dynamic reconfiguration signals reconfig_fromgxb and reconfig_togxb. This block supports offset cancellation. The design compiles without the Transceiver Reconfiguration Controller, but it cannot function correctly in hardware.

For information about the number of reconfiguration interfaces you must configure in your Arria® V, Cyclone® V , or Stratix® V dynamic reconfiguration block, refer to the descriptions of the reconfig_togxb and reconfig_fromgxb signals. An informational message in the RapidIO parameter editor tells you the required number of reconfiguration interfaces.
