•  Silicon Interfaces Announces the release of its new Verification Intellectual Property -USB 2.0 RVM VIP
Design and Reuse Headlines News - Monday, 24th October

CAMPBELL, Calif. - 24th October, 2005 - Silicon Interfaces, a high-end design services and leading provider for IPs in Europe, North America and Asia-Pacific, under their IP Development Program - Silicon Cores: Core to the Intelligent Systems™, today announced the availability of USB 2.0 RVM VIP (Reference Verification Methodology), (Verification) intellectual property (VIP). The SI60USBRVM10, USB 2.0 RVM VIP increases the portfolio of Silicon Interfaces Verification IP's.
Silicon Interface's USB 2.0 Vera RVM VIP is fully documented, off the shelf component for the Verification of the USB 2.0 compliant function controller. USB 2.0 Vera RVM VIP provides a concise, declarative mechanism to verify USB 2.0 Function Controller.
This VIP is developed using the Synopsys Vera Reuse Verification Methodology that is used in dynamic simulation of USB 2.0 based design.

The RVM methodology is based on the following cornerstones

•  Constrained random stimulus generation raises the abstraction level in test bench code.
•  DFV improves the observability of design errors by providing means for an abstract specification of the Device behavior using assertions.
•  Reusable test benches and reusable assertion-based checkers reduce the effort needed to verify complex Devices and interface protocols.
The objective of RVM methodology is to create a test environment with the following characteristics or features
•  Use functional coverage metrics to direct the verification effort and measure progress.
•  Maximum use of random stimulus.
•  Creation and use of reusable verification components.
•  Portability across various levels of abstraction of the DUT.
•  Portability from block-level to system-level.

The VIP provides a fast, accurate way to simplify and speed-up the device verification task in a complex design process, verification can take up to 70% of the development time.

USB 2.0 Vera RVM VIP speeds up the verification process providing a compelling cost and time to market, said Pervez Bharucha, Chief Technical Consultant for Synopsys verification technologies at Silicon Interfaces. Object Oriented Programming approach plays one of the key roles to achieve these goals. Writing a reusable code makes it easy for the Verification Engineer to apply the same tasks in various modules from project-to-project and code is maintainable.
