Intern Engineer: Development of tools for validation and analysis of MIPI I3C protocol F/M

**Location: Caen

Target sectors: Industrial IT / Computer Science / Electronics

Keywords: NFC, communication protocols, python, test infrastructure, object-oriented programming**

Context

The "Radio Firmware" team, based in Caen, is responsible for providing the embedded software (firmware) necessary for the operation of NFC and UWB components designed by NXP. These components, widely distributed, equip a majority of mobile phones and connected objects, enabling them to communicate (banking transactions, localization, data exchange, etc.). High-performance and automated testing tools and methods must constantly be developed and improved to ensure effective validation of this software.

We are looking for a final-year intern for a 6-month period in this area.

Missions

Mission proposed to the intern engineer:

The intern will contribute to the development of tools for the validation and analysis of the MIPI I3C (Improved Inter-Integrated Circuit) communication protocol. After a phase of familiarization with the tools and the technical framework, particularly by implementing data recording functionalities within our automated test bench, he/she will take charge of creating a decoder for a logic analyzer.

This project will proceed according to the following steps:

• Adding data recording functionalities: Definition of all sequences specific to the MIPI I3C protocol, adding data to the files generated by the test bench.
• Creation of unit tests for I3C functionalities: Design of the test architecture, software development, and validation.
• Creation of a decoder for a logic analyzer: Transposition of the protocol specification to an efficient decoding tool allowing easy analysis of MIPI I3C communication on a bus.
• Migration of functionalities: Transposition of test functionalities from a test bench developed in C++ to a test bench developed in Python.

This mission will allow the intern to mobilize skills in programming, diagnosis, and failure processing of industrial communication protocols, particularly in embedded systems subject to high robustness, performance, and energy saving requirements, as well as knowledge of validation processes in industrial environments.
