  • Title: The Revival of BIST: From Self-Test to Self-Healing

    Speaker: Prof. Hans-Joachim Wunderlich, University of Stuttgart, DEU

    Date: Tuesday, 28 Nov., 2017

    Abstract:

    Built-in self-test techniques have been around for 50 years. The early approaches were based on random pattern testing for cost minimization and have been improved over the years to reduce test time and increase fault coverage. Despite these efforts, logic BIST has been a niche application for many years due to concerns about hardware area costs, design and validation effort and the impact on timing and the functional behavior.

    With the high functional safety requirements in electronic mass markets like automotive, the situation has changed. BIST had to be extended from production and offline test to in-system runtime test. The appearance of multi-core SoCs and many-core processors, made modular and hierarchical approaches a necessity.

    As a next step, self-aware systems are found in automotive, industrial, or medical application domains which need to monitor their own state and the capabilities of the underlying hardware platform in addition to monitoring their environment. This comprises for instance timing or voltage margins, error rates and locations, or known faulty components. The knowledge of the hardware fitness is a requirement for qualified adaptation to changing system states and graceful degradation, for instance by voltage or frequency calibration, use of available redundancies, or isolation of known faulty modules.

    To capture the state of the hardware platform, a self-aware system integrates instrumentation and sensors to monitor and to examine the state of its hardware structures. The employed instrumentation spans from design-for-test and diagnosis features, fault-tolerant design, and different types of monitors to the required control and access mechanisms that interconnect them.

    Today we see the first steps towards hardware standards and functional approaches supporting in-field monitoring and calibration, self-awareness and fault management. The talk will cover the main challenges we have overcome in the past, and the challenges we are facing now in order to apply BIST in critical applications like automotive and medicine.

  • Title: Addressing Automotive Safety Challenge & Solutions

    Speaker: Dr. Yervant Zorian, Synopsys

    Date: Wendesday, 29 Nov., 2017

    Abstract:

    Given today’s fast growing automotive semiconductor industry, this keynote will discuss the trends, challenges and implications of automotive safety requirements on all aspects of the SOC lifecycle: design, silicon bring-up, volume production, and particularly in-system functional safety. Today’s automotive chips need multiple in-system self-test modes, such as power-on self-test and repair, periodic in-field self-test, advanced error correction, etc. This keynote will cover these specific in-system requirements and the benefits of selecting ISO 26262 certified solutions to ensure standardized functional safety, while accelerating time to market for automotive SOCs.

  • Title: A Foundry’s View of Hardware Security

    Speaker: Dr. Shih-Lien Lu, TSMC

    Date: Tuesday, 28 Nov., 2017

    Abstract:

    A system is as secure as its weakest link. Current computing systems employ a multiple-layer approach to build a trusted environment. At the bottom of this multi-layer approach is a hardware root of trust which other layers build upon. It is important to assure this root of trust is secure and free from any weakness. Recently there is surge of research topics on hardware security. In this talk we first narrow the topic a bit and outline a tighter definition of hardware security. We, then, focus on a few topics related to this tighter definition of hardware security including hardware Trojans and IC counterfeiting. On hardware Trojans, we first explain why it is so hard to prevent hardware Trojans. While we are at it we will argue why it is very unlikely for a reputable foundry such as TSMC to plant them. On IC counterfeiting, there have been work on employing Physically Unclonable Function (PUF) to prevent counterfeiting. In this talk we will explain the difference between testing of these hardware security elements from testing of standard logic elements. We will also clarify that foundry is in the best position to design and build these elements such as Physical Unclonable Functions (PUFs) and Physical Random Bits Generators (PRBGs).
