Software facilitates chip verification productivity.
January 7, 2009 -
VMM verification methodology lets chip developers use SystemVerilog to create verification environments using transaction-level, coverage-driven, constrained-random, and assertion-based techniques. In addition to multi-stream scenario generator, transactor iterator, and command-line options manager, solution incorporates Performance Analyzer application for analysis of shared design resources. Tests can be compiled and elaborated upon at once then selectively executed at run-time.

VMM Users Drive New Features in Expanded Release
Enhancements to Industry's Most Proven Verification Methodology Include New Base Classes and Performance Analyzer Application
MOUNTAIN VIEW, Calif., Dec. 17 -- Synopsys, Inc. (NASDAQ:SNPS), a world leader in software and IP for semiconductor design and manufacturing, today announced the release of an expanded version of VMM, the industry's most production-proven verification methodology. The updated release includes new, user-driven features, such as a multi-stream scenario generator, transactor iterator and command-line options manager. These features increase scalability from block to system-level, ease-of-use and verification productivity. A new Performance Analyzer application further improves productivity by enabling analysis of shared design resources. The enhancements to VMM streamline the development of today's increasingly complex verification environments.
"After a thorough evaluation of competing verification methodologies, we standardized on VMM to streamline verification of our IP and microcontrollers," said Sury Maturi, director of the Design Automation Group at National Semiconductor. "The new, expanded release of VMM includes a number of enhancements that will allow us to further reduce our verification cycles, such as the multi-stream scenario generator and new test structure, which enables us to create sophisticated controllable scenarios and, consequently, achieve greater scalability and reuse of stimulus."
"As an international provider of high-end functional verification consulting services, we have deployed VMM for our clients on a range of projects across the globe," said Jason Sprott, vice president of Consulting at Verilab. "Because of our significant level of hands-on experience with verification methodologies, we were in an excellent position to help guide the evolution of VMM and contribute to the enhancements in the latest release. It now enables even higher levels of scalability, simplifies implementation and is more capable than ever at helping design teams accelerate the verification process."
"A robust and production-proven methodology is a must in order to meet today's demanding project schedules, and a strong ecosystem is equally important for ease-of-adoption," said Michael Hoyt, president and chief executive officer of Paradigm Works. "VMM not only delivers the strongest ecosystem in the industry, it also offers a suite of extremely useful applications. We have been and will continue to be part of this growing ecosystem focused on delivering applications that improve verification productivity."
Increased Scalability
The new release of VMM includes a multi-stream scenario generator, which increases block to system-level scalability by enabling users to layer and control the multi-stream scenarios hierarchically. It provides an easy way to generate, control and schedule different heterogeneous transaction sequences. The execution of multi-stream scenarios creates coordinated stimulus on multiple channels anywhere in the verification environment.
Enhanced Ease-of-use
With VMM's new transactor iterator, users can now configure multiple transactors in an identical fashion using the same amount of code it takes to configure a single transactor, simplifying the transactor configuration process. Additionally, a new command-line options manager simplifies the task of managing complex verification environments within cross-functional teams by making it easier to check for run-time command-line options or options set through a set of option files.
Improved Productivity
A new application called Performance Analyzer now provides the ability to measure statistical functional coverage metrics, such as the utilization of shared resources, the response time of arbiter or slave devices, or the processing time of a functional block. The performance data can be queried and computed from multiple simulation results and performance metrics reported textually or graphically.
The latest release of VMM offers a new base class that enables test writers to compile and elaborate all tests at once then select, at run-time, which test to execute. This eliminates the need for a recompile of each test, thereby speeding regression turnaround time. In addition, a new channel recording and replay capability enables users to run entire regressions just once and perform playback later without stimulus generators for specific components of the verification environment.
"Synopsys and the EDA industry are seeing broad deployment of SystemVerilog," said Manoj Gandhi, senior vice president and general manager of the Verification Group at Synopsys. "We continue to provide technological leadership in this market with increased investments that address the growing verification challenges of our customers. The expanded release of VMM is the result of a successful and innovative collaboration between Synopsys, our customers and partners. It provides an excellent foundation for building a single, standardized verification methodology."
About VMM
The VMM methodology enables chip development teams to use SystemVerilog to create comprehensive verification environments using transaction-level, coverage-driven, constrained-random and assertion-based techniques, and specifies library building blocks for interoperable verification components. The latest enhancements to VMM are backward compatible with the previous version of VMM, compliant with SystemVerilog and entirely open source. The expanded release of VMM is available for immediate download at http://www.vmmcentral.org/.
