Starting in 2020, MIPI Alliance plans to host interoperability workshops for I3C v1.1.
While this could change in future, the minimal requirements to date have been the availability of a board with an I3C Device that can connect to other Devices via the three wires SDA, SCL, and GND. It’s also useful to have software (e.g., running on a laptop connected to the board and I3C Device) to interactively view transmitted and received bus communications, but this might not be required for Slaves.
Currently there are solutions working at 3.3V and 1.8V.
In general, any MIPI Alliance members who have I3C hardware ready to interop can participate.
MIPI arranges a particular I3C Interoperability Workshop event in response to requests from its membership.
There are three major outputs from a MIPI I3C Interoperability Workshop:
It is a MIPI Alliance sponsored event where different vendors bring their I3C implementations and check interoperation with other vendors.
