DVCon 2012: A 30 Minute Project Makeover Using Continuous Integration February 29, 2012
You've just spent a week working on a complex testbench change. You've regressed your changes and are ready to check them in. First, though, you pull in updates from other users and rerun regressions. Now you find that the testbench no longer compiles, or perhaps fails to run a basic test. You're late delivering your code and your manager is breathing down your neck. But it's not your fault! A Continuous Integration (CI) server can go a long way to preventing these situations. This paper describes the features and setup of one CI server (Jenkins) and how you can apply it to your design projects, with minimal effort. We consider both the technical and managerial challenges of using continuous integration. ( JL Gray , Gordon McGregor )

SNUG 2010: Interoperable Testbenches Using VMM TLM April 13, 2010
SOC’s are getting larger all the time and so is the challenge to verify these designs in a short period of time. This paper presents a transaction level-based methodology in the VMM to stan-dardize development of various pieces of a verification environment and the communication be-tween them. This methodology promotes reuse and helps integrate modules from various sources to interact together seamlessly.
DVCon 2010: Stimulating Scenarios in the OVM and VMM April 12, 2010
In this paper, advanced stimulus generation concepts, architecture, and motivation will be described. Tips for a successful stimulus generation implementation will be provided, and solutions from the VMM and OVM libraries will be compared and contrasted. ( Scott Roland , JL Gray )

SNUG 2010: Integrating e Verification IP in a VMM Testbench April 12, 2010
Modern testbenches often consist of components drawn from multiple languages. In many of these cases, multi-language and multi-methodology interaction is not well defined. In this paper, we will demonstrate the use of e verification components (eVCs) in a SystemVerilog/VMM testbench. Several complex issues arise when using SystemVerilog as the ‽primary” language. Initial simulator engine synchronization, random generation ordering, timing problems caused by program blocks, and methodology synchronization between the VMM and eRM will all be discussed. ( JL Gray , Adiel Khan [Synopsys] )
SNUG 2009: Using the New Features in VMM 1.1 for Multi-Stream Scenarios April 18, 2009
Today's verification solutions often require complex concurrent streams of stimulus controlled from higher level transactors or scenarios. The VMM 1.1 library has been enhanced to add this capability, and support the management of access to the resources shared by different stimulus streams, i.e. multiple streams providing stimulus to the same transactor. This paper describes the challenges faced in developing these new features, and takes a detailed look at how they are used in a VMM "multi-stream scenario" environment.
OCP-IP Article - OCP Profiles and Transactions January 5, 2009
Published in the DEC 2008, Vol 7 edition of the OCP-IP Newsletter (http://www.ocpip.org/)
This article demonstrates how two key aspects of OCP "profiles and transactions" were adopted as fundamental building blocks for the architecture of a verification component targeted at constrained-random validation of OCP components and systems. The article uses the Verilab OCP uVC as an example. This uVC is a mixed-language OCP compliant verification component that supports a major subset of Open Core Protocol Specification 2.2. (

Endian: From the Ground Up August 18, 2008
This document explores endianness using a coordinate system terminology, and explains common endian misconceptions as arising from coordinate system ambiguity. Topics covered are: The definition and properties of endian; the endian problem; independence of bit and byte endian; why bit significance and byte address must be managed in hardware; why byte significance must be managed in software.

Application Note: FPGA Protoyping in Verification Flows December 8, 2006
Hardware-assisted verification environments often make use of FPGAs to prototype the
ASIC in order to provide a faster alternative to simulation and allow software development to proceed in parallel with hardware design. This application note addresses the factors that should be taken into account in such a flow in order to maximize the effectiveness of the overall verification environment. (

The Myth of SystemVerilog Interoperability July 30, 2008
In this 45 minute presentation first given at DAC 2008, JL Gray, member of the Accellera VIP TSC and author of Cool Verification (www.coolverification.com) looks at the verification interoperability problem by examining SystemVerilog interoperability between simulators and functional differences between competing methodology libraries. JL will also discuss the likelihood SystemVerilog interoperability will move (unlike Santa and the Tooth Fairy) from myth to reality as a result of the efforts of the Accellera VIP TSC. ( JL Gray )
Getting Started with Requirements Based Verification June 17, 2008
Verification planning is an essential part of the chip design process, yet experience shows that it is seldom attempted with any rigor. Enthusiasm for the task tails off rapidly as soon as the "real work" of coding the testbench becomes feasible. Limited knowledge of how to do effective verification planning, low personal motivation and benefits, and lack of permission are common reasons for abandoning the planning early. Subsequent verification tends to be inefficient, impacting both the quality of the design and delivery schedule, and leading to a stressful and unsatisfying project experience for all involved.
In this one hour presentation first given at DAC 2008 in Anaheim, California, Dr. David Robinson from Verilab provides an introduction to Requirements Based Verification, a verification planning approach which aims for efficiency by allowing project stakeholders visibility into the size, scope, progress and risk of the overall verification process. Good risk-based visibility at all stages helps ensure that verification proceeds with few surprises.
This presentation is extracted from Verilab's Requirements Based Verification review process, and covers the following topics:
- Requirements Based Verification overview
- How to create good requirements
- Risk based prioritization
The presentation will be of interest to verification engineers and managers who would like to improve the efficiency of their verification efforts.
