Book Synopsis Low-cost and Efficient Fault Detection and Diagnosis Schemes for Modern Cores by : Javier Sebastian Carretero Casado
Download or read book Low-cost and Efficient Fault Detection and Diagnosis Schemes for Modern Cores written by Javier Sebastian Carretero Casado and published by . This book was released on 2015 with total page 253 pages. Available in PDF, EPUB and Kindle. Book excerpt: Continuous improvements in transistor scaling together with microarchitectural advances have made possible the widespread adoption of high-performance processors across all market segments. However, the growing reliability threats induced by technology scaling and by the complexity of designs are challenging the production of cheap yet robust systems. Soft error trends are haunting, especially for combinational logic, and parity and ECC codes are therefore becoming insufficient as combinational logic turns into the dominant source of soft errors. Furthermore, experts are warning about the need to also address intermittent and permanent faults during processor runtime, as increasing temperatures and device variations will accelerate inherent aging phenomena. These challenges specially threaten the commodity segments, which impose requirements that existing fault tolerance mechanisms cannot offer. Current techniques based on redundant execution were devised in a time when high penalties were assumed for the sake of high reliability levels. Novel light-weight techniques are therefore needed to enable fault protection in the mass market segments. The complexity of designs is making post-silicon validation extremely expensive. Validation costs exceed design costs, and the number of discovered bugs is growing, both during validation and once products hit the market. Fault localization and diagnosis are the biggest bottlenecks, magnified by huge detection latencies, limited internal observability, and costly server farms to generate test outputs. This thesis explores two directions to address some of the critical challenges introduced by unreliable technologies and by the limitations of current validation approaches. We first explore mechanisms for comprehensively detecting multiple sources of failures in modern processors during their lifetime (including transient, intermittent, permanent and also design bugs). Our solutions embrace a paradigm where fault tolerance is built based on exploiting high-level microarchitectural invariants that are reusable across designs, rather than relying on re-execution or ad-hoc block-level protection. To do so, we decompose the basic functionalities of processors into high-level tasks and propose three novel runtime verification solutions that combined enable global error detection: a computation/register dataflow checker, a memory dataflow checker, and a control flow checker. The techniques use the concept of end-to-end signatures and allow designers to adjust the fault coverage to their needs, by trading-off area, power and performance. Our fault injection studies reveal that our methods provide high coverage levels while causing significantly lower performance, power and area costs than existing techniques. Then, this thesis extends the applicability of the proposed error detection schemes to the validation phases. We present a fault localization and diagnosis solution for the memory dataflow by combining our error detection mechanism, a new low-cost logging mechanism and a diagnosis program. Selected internal activity is continuously traced and kept in a memory-resident log whose capacity can be expanded to suite validation needs. The solution can catch undiscovered bugs, reducing the dependence on simulation farms that compute golden outputs. Upon error detection, the diagnosis algorithm analyzes the log to automatically locate the bug, and also to determine its root cause. Our evaluations show that very high localization coverage and diagnosis accuracy can be obtained at very low performance and area costs. The net result is a simplification of current debugging practices, which are extremely manual, time consuming and cumbersome. Altogether, the integrated solutions proposed in this thesis capacitate the industry to deliver more reliable and correct processors as technology evolves into more complex designs and more vulnerable transistors.

Available in PDF, EPUB and Kindle. Book excerpt: The RV series of workshops brings together researchers from academia and industry who are interested in runtime verification. The goal of the RV workshops is to study the ability to apply lightweight formal verification during the execution of programs. This approach complements the offline use of formal methods which often use large resources. Runtime verification methods and tools include the instrumentation of code with pieces of software that can help to test and monitor it online and detect, and sometimes prevent, potential faults. RV 2009 was held on June 26-28 in Grenoble, France, adjacent to CAV 2009. The program included 11 accepted papers. Two invited talkswere given by Amir Pnueli on "Compositional Approach to Monitoring Linear Temporal Logic Properties" and Sriram Rajamani on "Verification, Testing and Statistics". The program also included three turorials.
Book Synopsis Post-silicon Bug Localization in Processors by : Sung Boem Park
Download or read book Post-silicon Bug Localization in Processors written by Sung Boem Park and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: For complex integrated circuits, pre-silicon verification alone is inadequate in ensuring that manufactured chips do not contain logic and electrical bugs. Post-silicon validation, which operates samples of manufactured chips in application environments to validate correct behaviors across specified operating conditions, is essential. According to industry reports, post-silicon validation is becoming very expensive. A major bottleneck in post-silicon validation is the bug localization step which involves identifying hardware bug locations and short functional stimuli that can expose detected bugs. For example, it may take several days to weeks to localize an electrical bug that may arise due to incorrect interactions between a design and the operating conditions. This dissertation presents IFRA (Instruction Footprint Recording & Analysis), a new technique for post-silicon bug localization in processors, which overcomes cost and scalability challenges of existing techniques. During normal operation of a processor in a post-silicon validation setup, special on-chip recorders collect information about flows of instructions through the processor and what the instructions did as they passed through various design blocks. Upon system failure, such as a crash, the recorded information is scanned out and analyzed offline using special self-consistency-based analysis techniques to localize hardware bugs. IFRA provides two major benefits over traditional techniques: (1) it does not require bugs to be reproduced at the system-level and (2) it does not require system-level simulation. Evaluation of IFRA on an open-source microarchitectural simulator modeling Alpha 21264 demonstrates high bug localization accuracy (96%) at low area overhead (1%). Applying IFRA to new microarchitectures can be challenging because it requires some degree of manual effort. This dissertation will also present a new BLoG (Bug Localization Graph) technique which is a step towards automated application of IFRA. Evaluation of BLoG-assisted IFRA on an industrial microarchitectural simulator modeling Intel Core i7, a state-of-the-art complex commercial processor, demonstrates its effectiveness (90% bug localization accuracy) and practicality.

Book Synopsis QED Post-silicon Validation and Debug by : Hai Lin
Download or read book QED Post-silicon Validation and Debug written by Hai Lin and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: During post-silicon validation and debug, manufactured integrated circuits (ICs) are tested in actual system environments to detect and fix design flaws (bugs). Traditional pre-silicon verification is inadequate; as a result, many critical bugs are detected only after ICs are manufactured (i.e., during post-silicon validation and debug). However, post-silicon validation and debug is challenging because traditional techniques are ad hoc (e.g., insertion of various Design for Debug structures based on various heuristics), and the associated costs are rising faster than design costs. These challenges are further magnified by the slowdown of silicon CMOS scaling, as ICs incorporate tremendous complexity to meet increasing demands for improvements in performance and energy efficiency. Examples include the use of multiple processor cores, co-processors, hardware accelerators, uncore components (defined as components in an SoC that are neither the processor cores nor the co-processors / accelerators; examples of uncore components include cache controllers, memory controllers, and interconnection networks), and power management units. This dissertation presents the Quick Error Detection (QED) technique to overcome post-silicon validation and debug challenges. QED is essential because long error detection latency, the time elapsed between the occurrence of an error caused by a bug and its manifestation as an observable failure, severely limits the effectiveness of existing post-silicon validation and debug approaches. Experimental results collected using several state-of-the-art commercial hardware platforms, as well as results obtained from simulations of various bug scenarios that occurred in commercial multi-core System-on-Chips (SoCs), demonstrate the effectiveness and practicality of QED: 1. QED improves error detection latencies by up to 9 orders of magnitude, from billions of clock cycles to very few clock cycles (generally fewer than 1,000 clock cycles for most bug scenarios). 2. QED enables up to 4-fold improvement in bug coverage (i.e., QED detects bugs that may be missed by traditional post-silicon validation approaches). 3. Symbolic Quick Error Detection (Symbolic QED) localizes difficult logic bugs automatically in a few hours (less than 7 hours for most bug scenarios), without requiring any additional hardware. Localizing a bug involves identifying a bug trace (defined as a sequence of inputs, e.g., instructions, that activates and detects the bug) and identifying the hardware design block where the bug is (possibly) located. This was demonstrated for an open-source multi-core SoC consisting of 500 millions transistors. In contrast, it might take days or weeks (or even months) of manual work, per bug, when traditional techniques are used. QED is effective for bugs inside processor cores, co-processors / software-programmable accelerators (which are components in an SoC that can be programmed using software to perform a specific set of functions, examples include graphic processing unit and digital signal processor), non-programmable hardware accelerators (which are components in a SoC that are designed to perform a pre-defined set of functions, but cannot be programmed using software, examples include accelerators for video or audio compression), and uncore components such as cache controllers, memory controllers, and interconnection networks. QED has been successfully used in industry during post-silicon validation and debug of a commercial multi-core SoC.
