Instructions for Minimum Change Migration
SMPTE 2022-5/6 RX Migration from v3.0 to v4.0
Port Changes
In SMPTE 2022-5/6 RX v4.0, a new feature was added which supports SMPTE 2022-7, where
the receiver core receives two identical/seamless AXI-Streams (Primary and Secondary) with
different header as configured by the user. The port changes related to the new feature are
shown in Table
The secondary AXI-Stream Slave Interface and Ethernet Packets Received Interface signal is
visible only when Seamless Switching feature is enabled in the core setting. By disabling the
Seamless Switching, only primary AXI-Stream is visible and is similar to SMPTE 2022-5/6 RX
v3.0 core which uses single Ethernet Link.
*prefix pri_ is for Primary and sec_ for Secondary
*prefix N is indicating channel number
