Frequent Contributor1. What happen if I don't instantiate this reconfiguration controller?
> The transceivers in the Cyclone V designs are configured with Altera Custom PHY IP. The Custom PHY IP requires two reconfiguration interfaces for external reconfiguration controller. That's the reason why this should instantiate.
2. What do I do with these two signals reconfig_togxb and reconfig_fromgxb if I don't instantiate the reconfiguration controller?
> Leave this bus disconnected if you are not using an external reconfiguration controller.
3. If I instantiate this controller, what are the parameters in the IP configurator:
Number of reconfiguration interfaces: 2 (ok from documentation)
Enable duty configuration: Checked or not?
> I'm not seeing this option in GUI, what Im seeing at my end is Enable duty cycle calibration.
Enable Analog controls: Checked or not?
> Turn on the Enable Analog controls option to enable VOD setting reconfiguration
Enable channel/PLL reconfiguration: Checked or not?
> Turn on the Enable channel/PLL reconfiguration option to allow the streamer-based reconfiguration process. This reconfiguration mode reconfigures the TX/RX data path, CDR settings, and TX PLL selection.
Enable PLL reconfiguration support block: Checked or not?
> Checked if only you enabled the Channel/PLL reconfiguration. When enabled, the Transceiver Reconfiguration Controller includes logic to perform PLL reconfiguration.
