Mentor Graphics Corp. (NASDAQ: MENT) and Cadence Design Systems, Inc. (NASDAQ: CDNS) recently released version two of the open-source Open Verification Methodology (OVM). OVM 2.0 includes the new OVM User Guide, which provides step-by-step guidelines to help users develop reusable, interoperable verification IP and hierarchical environments to facilitate plug-and-play verification. The 2.0 release extends the sequential stimulus mechanism in the OVM with transaction-level modeling (TLM) interfaces to improve the modularity and reuse of stimulus sequences. Other enhancements include direct support for parameterized classes in the OVM factory and built-in debug support for TLM connections throughout the hierarchy.
The OVM User Guide provides straightforward documentation on all aspects of the OVM, including an extensive review of TLM for verification, guidelines for developing reusable OVM verification components, instructions for building verification tests, and in-depth discussions on the more advanced features of the OVM. The guide also includes an extensive example showing how to apply these concepts to the creation of a full hierarchical verification environment, including tests that configure the environment and select the desired stimulus sequences to exercise the required functionality.
