MCTP over I3C
MCTP (Management Component Transport Protocol) over I3C is a transport binding that enables standardized communication between system management controllers and peripherals using the MIPI I3C (Improved Inter-Integrated Circuit) bus.
MCTP is a transport-agnostic protocol, meaning it can operate over various physical layers like PCIe, SMBus/I²C, UART, and Ethernet. When using I3C, MCTP benefits from its higher speed, dynamic addressing, and in-band interrupt support, making it a more efficient alternative to I²C/SMBus.
Acute Technology offers logic analyzers with support of MCTP over I²C / MCTP over I3C / MCTP over SMBus decoding.

MCTP over I3C Decoding Setup Steps
1. Click Quick Settings or Add Protocol Decode to select a protocol for logic analyzer capture.
2. Select MCTP over I3C for decoding.
3. If you use Quick Settings, the system will recommend configurations for trigger type, sampling rate, voltage threshold, and channel settings.
4. Click the icon to access the Decode Settings screen.
Decode Settings
Channel: Specify the Logic Analyzer channel number connected to each signal end on the device under test.
Destination Address Configuration: Set the device address and its corresponding protocol.
Advanced Decode Setting: Display the detailed interpretation of the raw data.
