Background
Highvoltage (HV) gate drivers for automotive traction inverters increasingly rely on multidie architectures where galvanic isolation is required to ensure safety and reliable operation. Efficient communication across isolated domains is essential to guarantee realtime coordination error robustness and functional safety compliance.
Objective
The objective of this thesis is to design and verify a new digital architecture enabling communication and control between galvanically isolated dies within an HV Gate Driver IC. The work aims to overcome the limitations of the current implementation by introducing a dedicated communication protocol and enhanced control mechanisms.
Thesis Description
The project is structured into three main phases:
Architectural Analysis
Perform a detailed review of the existing communication architecture.
Identify structural limitations performance bottlenecks and operational constraints.
Define systemlevel requirements for the nextgeneration solution.
Digital Architecture Definition and RTL Implementation
Propose a new communication protocol optimized for isolated multidie systems.
Design advanced mechanisms for Synchronization error detection monitoring and recovery
Arbitration of communication events over a single magnetic coil
Implement the proposed architecture in RTL including Data encoding/decoding modules Control units Channel monitoring blocks Recovery logic
Functional Verification (UVM)
Develop a UVM-based simulation environment.
Evaluate system performance in terms of: Latency Throughput Event collision handling
Validate protocol robustness and behavior under fault conditions.
Expected Outcome
The proposed work will establish the foundation for a new generation of HV Gate Drivers enabling improved robustness performance and scalability of isolated multidie communication.
