Title: "The goal is to design a hardware solution that allows: Detecting and monitoring voltage spikes on the 54 V input power supply of computing blades. 

Your missions:

• Defining a configurable trigger threshold (hardware or software). 
• Integrating an alarm system that reports when an event has occurred (GPIO, I²C, UART, CAN, or others).
• Timestamping detected spikes, ideally with microsecond precision or better.
• Enabling a protection circuit to be activated if excessively high voltage peaks are detected.
• Evaluating the minimal impact on the 54 V line (very low load, very low loss).
• Proposing a testable prototype on our HPC platform. 
• Work Required Needs and Constraints Analysis Architecture Choice Cost analysis, ease of integration, precision, responsiveness.
• HW Module Design Schematic entry Component selection (sense resistors, isolators, ADCs, comparators, microcontroller/FPGA, etc.).
• PCB design (optional, depending on internship duration).
•  Alarm System Implementation Interface definition (GPIO, I²C, UART, etc.). Event register implementation.
• Possibility of a circular buffer to retain multiple events.
• Firmware Development Threshold management.
• Timestamping (RTC or external synchronization).
• Communication to the blade or to a supervision system.
• Testing and Validation Stress tests on a 54 V power supply bench.
• Event capture and comparison with an oscilloscope (reference).
• Reliability and repeatability analysis.
• Documentation Design dossier.
• Integration guide for HPC teams.
• Final report detailing the chosen solution and any potential limitations. 

Required Skills:

Knowledge in analog and digital electronics. 

Understanding of power converters.

Use of tools: oscilloscope, analyzers, Cadence CAD environment. Knowledge of microcontrollers, FPGA, I²C/SPI/UART protocols.

Rigorousness and autonomy. Interest in motherboards and complex design

Let’s grow together.
