OVM World Collaborates on Accellera's Industry Solution for VIP Interoperability

Mentor Graphics (NASDAQ: MENT) and Cadence Design Systems, Inc.
(NASDAQ: CDNS) today announced that the Accellera guide for
verification IP (VIP) interoperability, currently in draft form,
was enabled by technology contributions provided by both companies
in open source form, and served as a basis for the reference
implementation of the Accellera VIP Technical Sub-Committee (TSC)
"Best Practices" guide. The guide provides recommendations for
interoperability between verification components compliant with the
Open Verification Methodology (OVM) and those developed using
legacy methodologies such as the approach documented in the
Verification Methodology Manual (VMM).
Historically, advanced verification users have had to invest a
great deal of time and effort to develop verification environments
with VIP from different sources. At the same time that the
Accellera VIP TSC was framing the requirements for an
interoperability solution, Cadence� and Mentor, working with
leading customers, members of the OVM Advisory Group (OAG), and
other industry participants, developed a set of library components
fulfilling these requirements. This reference implementation was a
key to validating the draft Accellera interoperability guide, which
incorporates many portions of the documentation developed by
Mentor, Cadence, and their OVM World partners.
"Our customers embraced the OVM very quickly when it was
introduced two years ago, but communicated clearly that they wanted
to include legacy VIP without having to re-write it from scratch,"
said Dennis Brophy, director of strategic business development at
Mentor Graphics. "We took a lead role in Accellera to define the
industry requirements while working with our OVM partners to
develop an interoperability solution. We are pleased to see the
results of our efforts reflected in the draft guide that Accellera
is in the process of making a standard."
All aspects of the reference implementation are compliant with
IEEE Std. 1800-2005 SystemVerilog and have been thoroughly verified
using OVM 2.0.1 on the Cadence Incisive� and Mentor Questa
verification solutions. The VIP interoperability approach
documented in the draft Accellera guide enables users to integrate
VIP written in standard IEEE verification and modeling languages
and legacy methodologies. This minimizes the need to re-write
existing VIP when setting up an OVM-based verification environment,
a clear savings in cost and time to market for users.
"With our long history of support for SystemC models and e-based
verification, our customers required a solution that spanned these
two languages as well as SystemVerilog," said Stan Krolikoski,
group director, standards and ecosystem at Cadence. "Our leadership
in the Accellera VIP TSC ensured that the scope of interoperability
would span multiple languages and multiple methodologies. The OVM
is robust enough to provide a complete solution for all of our
customers, so we strongly support the draft Accellera
interoperability guide and its recommended best practices."
About the Open Verification Methodology
The Open Verification Methodology is the first open,
language-interoperable, verification methodology in the industry.
It provides a methodology and accompanying libraries that allow
users to create modular, reusable verification environments in
which components communicate with each other via standard
transaction-level modeling interfaces. It also enables intra- and
inter-company reuse through a common methodology and classes for
virtual sequences and block-to-system reuse, and full integration
with other languages commonly used in production flows. The OVM and
OVM World began in August 2007 as a joint effort by Cadence Design
Systems and Mentor Graphics.
