Mentor Graphics releases 0-In CDC version 3.0 to support verification needs of larger, more complex designs

WILSONVILLE, USA: Mentor Graphics Corp. has announced the immediate availability of the 0-In CDC tool version 3.0, the industry's most complete and effective solution for clock domain crossing verification.

The patented technology in the 0-In CDC tool enables comprehensive analysis and verification of clock domains, synchronization, protocols, and reconvergence, using a combination of static formal verification and simulation in a highly-automated flow. As a result, the 0-In CDC tool enables verification of the most complex designs, with little user effort.

The 0-In CDC v3.0 tool supports SystemVerilog, Verilog, and VHDL with a wide variety of design styles and synchronization methods. In version 3.0, the 0-In CDC tool supports top-down, bottom-up, and mixed approaches for hierarchical analysis, and gives the user more control over the verification process.

The 0-In CDC v3.0 tool includes patented technology that enables verification of the effects of metastability and reconvergence during simulation. In addition, the 0-In CDC v3.0 tool exports data to Mentor’s Unified Coverage Data Base (UCDB). Together, these enhancements enable users to verify larger and more complex designs and integrate the results into a complete coverage-driven verification flow.

“Clock-domain crossing verification is an increasingly-difficult challenge in today's designs, which have large numbers of typically asynchronous clock domains. It is a complex verification problem that requires a multi-faceted solution,” said John Lenyo, general manager, Design Verification Technology (DVT) division.

“The 0-In CDC tool provides such a solution by combining our best-in-class formal technology with the industry-leading Questa verification platform to attack the problem from several directions. Version 3.0 builds on extensive customer experience over the past 5 years to provide even greater flexibility and power.”

Questa functional verification platform
The Questa functional verification platform combines high performance and high capacity with the most comprehensive verification capabilities in the industry.

Assertion-based Verification (ABV), intelligent testbench automation, Multi-view Verification Components (MVCs), and Coverage-driven Verification (CDV) are supported natively by the Questa platform’s high-performance assertion engine; a modern, high-performance constraint solver; and extensive functional coverage features, including verification management leveraging the Unified Coverage Database (UCDB).

Verification of low power design functionality can be proven in an RTL environment with power-aware functional verification. This full set of advanced verification functionality is enabled by a flexible Open Verification Methodology (OVM) that delivers unrivaled language and feature support in any design and verification flow.
