technical program committee : ANGHEL L., DI NATALE Giorgio

Summary: DFT is an annual Symposium providing an open forum for presentations in the field of defect and fault tolerance in VLSI and nanotechnology systems inclusive of emerging technologies. One of the unique features of this symposium is to combine new academic research with state-of-the-art industrial data, necessary ingredients for significant advances in this field. All aspects of design, manufacturing, test, reliability, and availability that are affected by defects during manufacturing and by faults during system operation are of interest.

IEEE International Test Conference

Venue: Washington DC, USA
Date: November 3-5, 2020

steering committee member : DI NATALE Giorgio technical program committee : VATAJELU E.I.

Summary: International Test Conference, the cornerstone of TestWeek™ events, is the world’s premier conference dedicated to the electronic test of devices, boards and systems-covering the complete cycle from design verification, test, diagnosis, failure analysis and back to process and design improvement. At ITC, test and design professionals can confront the challenges the industry faces, and learn how these challenges are being addressed by the combined efforts of academia, design tool and equipment suppliers, designers, and test engineers.

As technology node continues to shrink to achieve higher performance at high density, it has become extremely challenging to handle the effects of Process, Voltage, Temperature and Aging (PVTA) variations. The stringent requirement of achieving higher performance while maintaining the reliability of the design has become an important concern especially for the energy-efficient designs. The traditional approach of adding pessimistic timing margins to assure all operating points under worst case conditions is not feasible in advanced technology nodes due to the huge impact on design costs. In this thesis work, on-chip reliability and performance monitors as well as adaptive compensation techniques are investigated to address these challenges in the digital circuit design. Internally as well as externally situated monitors are evaluated for the accuracy of detection of PVTA variations. A novel externally situated timing monitor is proposed to detect PVTA variations accurately without impacting the timing closure of the reference design. A detailed analysis has been presented on the investigation of robustness of digital circuits using In-Situ Monitors emphasizing detection of global and local process variations, aging variations and cost impact of insertion of monitors on performance, power and area. For these analyses, measurements and simulation results are demonstrated using three different digital circuits implemented and fabricated in 28nm FDSOI CMOS technology of STMicroelectronics. Closed-loop adaptive voltage and body-bias compensation schemes have been proposed with In-Situ Monitors, and manufactured product results are analyzed.
