报告题目：LSI Testing: A Core Technology to a Successful Semiconductor Industry

工作单位：日本九州工业大学

报告简介：

The semiconductor industry is exposed to shrinking feature sizes, growing circuit complexity, increasing clock speeds, and decreasing power supply voltages. In addition to significant impact on LSI design and manufacturing, these factors also have a profound impact on LSI testing, a complex process for separating defective chips from defect-free ones. The major challenges to LSI testing are low test quality, high test cost, and excessive test power. These challenges have led to new chances of innovations in LSI testing, characterized by cell-aware test generation, test compression, and power-aware testing. This talk will review these challenges and chances. Furthermore, this talk will reveal the role of LSI testing in the semiconductor business chain, so as to explain why LSI testing is a core technology to a successful semiconductor industry.

报告题目：On the implementation of boundary scan design with embedded time-to-digital converter in a 3D stacked IC

工作单位：Tokushima University

报告简介：

A defective TSV may cause a small delay that is hard to be detected using logic testing. We have proposed a boundary scan design with an embedded time-to-digital converter circuit to detect delay faults in interconnects. The proposed design was implemented in a prototype 3D IC stacked by TSVs with different diameters. The measurement results show that the proposed delay testable circuit can detect both logic errors that occurred in TSVs with smaller than standard diameters and significant signal delay through a TSV with no logic error.

报告题目：SASL-JTAG: A Light-Weight Dependable Test Access Mechanism for Edge Devices

工作单位：Ehime University

报告简介：

As the connected devices permeate the human’s daily life, their reliability and security become paramount. JTAG known formally as the IEEE1149.1 Boundary Scan Standard is a widely used test access mechanism for testing, diagnosis and system debugging provides an improved reliability. However, its security vulnerabilities could potentially be a backdoor to cyberattacks, especially in low-performance and cost-sensitive IoT devices. In this work, we propose a lightweight JTAG authentication scheme named the SASL-JTAG, to addresses the performance imbalance issue of IoT systems for enhancing the dependability of edge devices. The architecture of the SASL-JTAG authentication is designed and implemented on an FPGA to verify its functionality and evaluate hardware overhead. SASL-JTAG offers a cost-effective and scalable solution for securing JTAG systems in IoT devices while ensuring high reliability.

工作单位：Kyushu Institute of Technology

报告简介：

The extreme compute demand of Machine-Learning (ML) applications pushes the development of ever more powerful Data-Parallel AI Accelerators. This talk explains how to leverage these Compute Accelerators to achieve High-Performance VLSI Timing Simulations, a core component of Electronic Design Automation (EDA) tools needed for the development and analysis of today's complex System-on-Chips. This timing simulator delivers performances several orders of magnitude higher than conventional approaches and enables many new applications. This talk shows three example applications from the fields of scan-test power analysis, small delay fault simulation and diagnosis, as well as AI accelerator resilience analysis.

报告题目：A Novel High Performance Scan-Test-Aware Hardened Latch Design with Improved Soft-Error Tolerability

工作单位：安徽理工大学

报告简介：

The continuous pursuing of smaller technology nodes makes modern Integrated Circuits (ICs) more and more susceptible to soft-errors. Many radiation-hardened latch designs have been proposed to tolerate soft-errors for reliable LSI designs. However, these existing hardened latches can suffer from reliability issues after production because production defects in such hardened latches are difficult to detect with conventional scan testing. In our previous works, we improved the defect detectability of these hardened latches by adding design-for-test (DFT) technique. A hardened latch design, called high performance scan-test-aware hardened latch (HP-STAHL), was proposed for higher defect detectability, higher soft-error tolerability, and lower propagation delay. However, the added DFT structure in HP-STAHL can partially reduce its soft-error tolerability. In this paper, we propose a novel high performance scan-test-aware hardened latch design with improved soft-error tolerability (HP-STAHL-I) by applying a novel design to offset the reduced soft-error tolerability. Simulation results show that HP-STAHL-I provides higher soft-error tolerability than HP-STAHL. HP-STAHL-I also has lower delay and power delay product (PDP) than the standard latch, demonstrating its high performance.

报告题目：Cutting Costs in IC Testing with Machine Learning

工作单位：安徽大学

报告简介：

As the size of VLSI circuits continues to shrink and lithography technology advances, the complexity of system-on-chip (SoC) design, system packaging, power management strategies, and signal integrity issues are becoming increasingly prominent, resulting in increased testing time and costs for the entire circuit system. The key challenge in today's testing process is how to reduce integrated circuit testing costs without compromising testing quality. To achieve the optimal solution between testing costs and testing quality, research on integrated circuit testing vector optimization methods is necessary. To address the critical issues of testing time, testing costs, testing quality, and fault coverage that are urgently needed in testing, research is conducted in areas such as machine learning, data mining, database establishment, and vector optimization to achieve cost savings in testing.
