SDI II Tx Instances

Hi,

As I understand it, you observed some errors when trying to merge the reconfiguration interfaces for simplex instances. For your information, the XCVR_RECONFIG_GROUP assignment is to merge two simplex TX and RX into the one physical transceiver channel. For example, in your design, you have one TX only instance and one RX only instance. By using this assignment, you can merge them into a single transceiver channel to save resource provided all the requirements in Intel Cyclone 10 GX Transceiver PHY User Guide -> "Rules for Merging Reconfiguration Interfaces Across Multiple IP Cores" are met.

I notice that you are assigning the XCVR_RECONFIG_GROUP to two TX instances. Note that the same group is for one TX and one RX. You may refer to Intel Cyclone 10 GX Transceiver PHY User Guide -> "Rules for Merging Reconfiguration Interfaces Across Multiple IP Cores" for further details.

Please let me know if there is any concern. Thank you.

Best regards,
