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.

Download or read book Variance Validation for Post silicon Debugging in Network on Chip written by Jiayong Liu and published by . This book was released on 2013 with total page 99 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since more complex components are integrated into a single chip and scale of chip goes far beyond, pre-silicon verification is getting hard to achieve full coverage at chip level and catch design bugs under physical conditions. As a complementary checking step, post-silicon validation has demonstrated its importance in verifying chip functionality. But still, the task of post-silicon validation is extremely difficult, especially for complex designs such as network on chip. In this thesis, a novel on-chip validation method based on the concept of variance validation is proposed to facilitate the process of post-silicon validation targeting the network on chip platform. Cores are paired and tagged as a functional core and a validating core in each pair. Variances are created for programs executed in each pair of cores. By comparing the outputs from each pair of cores, the method enables at-speed on-chip validation for core-based architectures and helps detect functional bugs after chip manufacturing. With little effort, the method can be extended to support reliable system design. Experiments are carried out and effectiveness of the proposed variance validation method is demonstrated by simulation results.

Download or read book Principles of Verifiable RTL Design written by Lionel Bening and published by Springer Science & Business Media. This book was released on 2001-05-31 with total page 297 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first edition of Principles of Verifiable RTL Design offered a common sense method for simplifying and unifying assertion specification by creating a set of predefined specification modules that could be instantiated within the designer's RTL. Since the release of the first edition, an entire industry-wide initiative for assertion specification has emerged based on ideas presented in the first edition. This initiative, known as the Open Verification Library Initiative (www.verificationlib.org), provides an assertion interface standard that enables the design engineer to capture many interesting properties of the design and precludes the need to introduce new HDL constructs (i.e., extensions to Verilog are not required). Furthermore, this standard enables the design engineer to `specify once,' then target the same RTL assertion specification over multiple verification processes, such as traditional simulation, semi-formal and formal verification tools. The Open Verification Library Initiative is an empowering technology that will benefit design and verification engineers while providing unity to the EDA community (e.g., providers of testbench generation tools, traditional simulators, commercial assertion checking support tools, symbolic simulation, and semi-formal and formal verification tools). The second edition of Principles of Verifiable RTL Design expands the discussion of assertion specification by including a new chapter entitled `Coverage, Events and Assertions'. All assertions exampled are aligned with the Open Verification Library Initiative proposed standard. Furthermore, the second edition provides expanded discussions on the following topics: start-up verification; the place for 4-state simulation; race conditions; RTL-style-synthesizable RTL (unambiguous mapping to gates); more `bad stuff'. The goal of the second edition is to keep the topic current. Principles of Verifiable RTL Design, A Functional Coding Style Supporting Verification Processes, Second Edition tells you how you can write Verilog to describe chip designs at the RTL level in a manner that cooperates with verification processes. This cooperation can return an order of magnitude improvement in performance and capacity from tools such as simulation and equivalence checkers. It reduces the labor costs of coverage and formal model checking by facilitating communication between the design engineer and the verification engineer. It also orients the RTL style to provide more useful results from the overall verification process.

Available in PDF, EPUB and Kindle. Book excerpt: This book provides an in-depth overview of on chip instrumentation technologies and various approaches taken in adding instrumentation to System on Chip (ASIC, ASSP, FPGA, etc.) design that are collectively becoming known as Design for Debug (DfD). On chip instruments are hardware based blocks that are added to a design for the specific purpose and improving the visibility of internal or embedded portions of the design (specific instruction flow in a processor, bus transaction in an on chip bus as examples) to improve the analysis or optimization capabilities for a SoC. DfD is the methodology and infrastructure that surrounds the instrumentation. Coverage includes specific design examples and discussion of implementations and DfD tradeoffs in a decision to design or select instrumentation or SoC that include instrumentation. Although the focus will be on hardware implementations, software and tools will be discussed in some detail.

Download or read book A Reconfigurable Post silicon Debug Infrastructure for Systems on chip written by and published by . This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: As the level of integrated circuit (IC) complexity continues to increase, the post-silicon validation stage is becoming a large component of the overall development cost. To address this, we propose a reconfigurable post-silicon debug infrastructure that enhances the post-silicon validation process by enabling the observation and control of signals that are internal to the manufactured device. The infrastructure is composed of dedicated programmable logic and programmable access networks. Our reconfigurable infrastructure enables not only the diagnoses of bugs; it also allows the detection and potential correction of errors in normal operation. In this thesis we describe the architecture, implementation and operation of our new infrastructure. Furthermore, we identify and address three key challenges arising from the implementation of this infrastructure. Our results demonstrate that it is possible to implement an effective reconfigurable post-silicon infrastructure that is able to observe and control circuits operating at full speed, with an area overhead of between 5% and 10% for many of our target ICs.

Download or read book Formal Verification written by Erik Seligman and published by Elsevier. This book was released on 2023-05-27 with total page 426 pages. Available in PDF, EPUB and Kindle. Book excerpt: Formal Verification: An Essential Toolkit for Modern VLSI Design, Second Edition presents practical approaches for design and validation, with hands-on advice to help working engineers integrate these techniques into their work. Formal Verification (FV) enables a designer to directly analyze and mathematically explore the quality or other aspects of a Register Transfer Level (RTL) design without using simulations. This can reduce time spent validating designs and more quickly reach a final design for manufacturing. Building on a basic knowledge of SystemVerilog, this book demystifies FV and presents the practical applications that are bringing it into mainstream design and validation processes. New sections cover advanced techniques, and a new chapter, The Road To Formal Signoff, emphasizes techniques used when replacing simulation work with Formal Verification. After reading this book, readers will be prepared to introduce FV in their organization to effectively deploy FV techniques that increase design and validation productivity.
