Generating Hardware Assertion Checkers


Book Description

Assertion-based design is a powerful new paradigm that is facilitating quality improvement in electronic design. Assertions are statements used to describe properties of the design (I.e., design intent), that can be included to actively check correctness throughout the design cycle and even the lifecycle of the product. With the appearance of two new languages, PSL and SVA, assertions have already started to improve verification quality and productivity. This is the first book that presents an “under-the-hood” view of generating assertion checkers, and as such provides a unique and consistent perspective on employing assertions in major areas, such as: specification, verification, debugging, on-line monitoring and design quality improvement.




Principles of Verifiable RTL Design


Book Description

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.

A Roadmap for Formal Property Verification


Book Description

Integrating formal property verification (FPV) into an existing design process raises several interesting questions. This book develops the answers to these questions and fits them into a roadmap for formal property verification – a roadmap that shows how to glue FPV technology into the traditional validation flow. The book explores the key issues in this powerful technology through simple examples that mostly require no background on formal methods.




Assertion-Based Design


Book Description

There is much excitement in the design and verification community about assertion-based design. The question is, who should study assertion-based design? The emphatic answer is, both design and verification engineers. What may be unintuitive to many design engineers is that adding assertions to RTL code will actually reduce design time, while better documenting design intent. Every design engineer should read this book! Design engineers that add assertions to their design will not only reduce the time needed to complete a design, they will also reduce the number of interruptions from verification engineers to answer questions about design intent and to address verification suite mistakes. With design assertions in place, the majority of the interruptions from verification engineers will be related to actual design problems and the error feedback provided will be more useful to help identify design flaws. A design engineer who does not add assertions to the RTL code will spend more time with verification engineers explaining the design functionality and intended interface requirements, knowledge that is needed by the verification engineer to complete the job of testing the design.




A Practical Guide for SystemVerilog Assertions


Book Description

SystemVerilog language consists of three categories of features -- Design, Assertions and Testbench. Assertions add a whole new dimension to the ASIC verification process. Engineers are used to writing testbenches in verilog that help verify their design. Verilog is a procedural language and is very limited in capabilities to handle the complex ASICs built today. SystemVerilog assertions (SVA) is a declarative language. The temporal nature of the language provides excellent control over time and allows mulitple processes to execute simultaneously. This provides the engineers a very strong tool to solve their verification problems. The language is still new and the thinking is very different from the user's perspective when compared to standard verilog language. There is not enough expertise or intellectual property available as of today in the field. While the language has been defined very well, there is no practical guide that shows how to use the language to solve real verification problems. This book is a practical guide that will help people to understand this new language and adopt assertion based verification methodology quickly.

Writing Testbenches: Functional Verification of HDL Models


Book Description

mental improvements during the same period. What is clearly needed in verification techniques and technology is the equivalent of a synthesis productivity breakthrough. In the second edition of Writing Testbenches, Bergeron raises the verification level of abstraction by introducing coverage-driven constrained-random transaction-level self-checking testbenches all made possible through the introduction of hardware verification languages (HVLs), such as e from Verisity and OpenVera from Synopsys. The state-of-art methodologies described in Writing Test benches will contribute greatly to the much-needed equivalent of a synthesis breakthrough in verification productivity. I not only highly recommend this book, but also I think it should be required reading by anyone involved in design and verification of today's ASIC, SoCs and systems. Harry Foster Chief Architect Verplex Systems, Inc. xviii Writing Testbenches: Functional Verification of HDL Models PREFACE If you survey hardware design groups, you will learn that between 60% and 80% of their effort is now dedicated to verification.
