OpenMORE RTL Rule Checker from Interra Accelerates Evaluation and Assessment of Reusable IP From Months to Days
Mentor Graphics Endorses Third-Party Tool to Address Growing Popularity of OpenMORE Program

IP2000, Santa Clara, Calif. - March 20, 2000 - Mentor Graphics Corp. (NASDAQ: MENT) co-developer of the OpenMORE (Open Measure of Reuse Excellence) reference assessment program, today endorsed the SpyGlass? RTL Rule Checker from Interra, Inc. to accelerate evaluation and assessment of reusable, OpenMORE-rated intellectual property (IP). SpyGlass software, with the OpenMORE Rule Deck, automatically checks RTL code for design rule violations for different aspects of the design, including reusability, verification, ASIC requirements and test according to a subset of the design rules and guidelines outlined by the OpenMORE rating program.

The SpyGlass RTL Rule Checker accesses design rules contained in a separate rule deck. The OpenMORE rule deck captures and enables rule checking for the software checkable subset of the more than 200 rules and guidelines for design and verification for soft, firm and hard IP outlined in the Reuse Methodology Manual (RMM) Second Edition, jointly-authored by Mentor and Synopsys. The remaining rules and guidelines are checked manually. The SpyGlass engine quickly evaluates and assesses core quality, providing design engineers with instant access to information on reusable core quality. Output includes simple listing of violations, graphical reports and also a conclusive reusability "score" based on the OpenMORE program.

"SpyGlass slashes a traditionally lengthy IP assessment process from months to days," said Tom Kozas, vice president of EDA marketing for Interra, Inc. "The SpyGlass RTL Rule-checker platform is the industry's fastest, executing over a million design rule violation tests per minute, accelerating the entire IP evaluation and assessment process."

"We are beginning to use Interra's SpyGlass to document and enforce our internal IP rules," said Mike Maul, director of design methodology at National Semiconductor. "Adding OpenMORE support to the Spyglass rule-checker will significantly expand our IP capabilities by allowing us to apply a consistent set of procedures and standards to ensure greater quality in our IP assessment, support and development efforts."

The SpyGlass RTL-rule checker software evaluates and automates checks of soft IP according to a subset of the 180 rules and guidelines as described in the RMM and VSIA Deliverables Documentation. OpenMORE then uses assigned weightings and percentages to calculate an OpenMORE score. The higher the percentage score, the greater the confidence IP customers will have that the IP core will readily integrate into a System-on-Chip design.

"To further widespread industry acceptance of the OpenMORE reusability guidelines, we wanted to endorse an automated checking mechanism to accelerate the IP evaluation and rating process," said Pierre Bricaud, director of marketing for the Mentor Graphics Intellectual Property Division and co-author of the Reuse Methodology Manual. "Design rule checkers like SpyGlass enable comprehensive code compliance evaluation and are a critical success factor in implementing an effective reuse methodology."

Bricaud continued, "In less than a year, more than 500 users have adopted OpenMORE as the standard measure for reusable IP quality. To meet this strong increase in demand requires more partnerships with third-party tool vendors that offer relevant experience in design reuse methodologies. As collective design reuse leaders, we can help solve the problems associated with designing SoC solutions."
