Learning objectives
The course will first address the problem of fault modeling, with reference to the automotive environment, to then study testing, design testability and hardware in the loop approaches. Then, onboard monitoring and diagnosis will be addressed, to finally study fault tolerant techniques for reliable systems’ design. The course will include laboratory experiences, and possible seminars given by experts in the field from the industrial world.
Prerequisites
Basic concepts of digital electronics.
Course unit content
Effects of resistive bridging faults affecting the clock distribution of ICs implemented by scaled technologies.
Effects of crosstalk fault on the bus lines of ICs implemented by scaled technologies, and traditional techniques to mitigate the effects of crosstalk faults.
Generation of transient faults and soft errors in data-paths of ICs implemented by scaled technologies. Methodologies to increase the robustness of combinational circuits and memory elements.
Introduction to main degradation phenomena affecting ICs implemented by scaled technologies, and their impact on circuits’ reliability. Design approaches to mitigate the impact of degradation phenomena on circuits’ reliability.
Error Correcting Codes: Introduction to Linear Parity Check Codes; Single Error Correction Hamming Codes; Single Error Correction/Double Error Detection Hsiao Codes; Encoding and Decoding Circuits.
Introduction to Hardware-in-the-Loop testing technique.
The course includes practice sessions in laboratories on: Electrical level simulations of resistive bridging faults, crosstalk faults and transient faults, and analysis of their effects in some circuits of interest.
