Unified Coverage

• Exponentially growing design complexity
• Disconnected workflows hampering efficiency
• Delayed discovery of critical issues
• Resource-intensive coverage closure
• Risk of missing vital verification scenarios during requirement changes

Teams struggle with resource-intensive coverage closure and risk missing critical verification scenarios when requirements change.

The journey begins with intelligent planning through the VIQ Testplan Author and Polarion ALM integration. This powerful combination creates an early-warning system that automatically tracks requirement changes and their impact on verification scenarios, ensuring teams stay ahead of potential issues before they become costly problems.

At the heart of this revolution lies the unified coverage database (UCDB), serving as the foundation for advanced analytics and AI-driven insights. This central nervous system powers comprehensive visualization and dynamic analysis capabilities, transforming raw data into actionable intelligence through:

• Comprehensive coverage visualization
• Dynamic analysis capabilities
• Intelligent gap identification
• Real-time progress tracking

Breaking Through Coverage Barriers

The solution introduces game-changing acceleration technologies through the Questa One Sim Coverage Acceleration (QCX) and Visualizer Coverage Debug Tool. These innovations revolutionize how teams achieve coverage goals, enabling dynamic debug sessions and intelligent test generation that significantly reduce time to coverage closure.

Key benefits that matter:

• Earlier detection of coverage gaps
• Significantly reduced time to coverage closure
• Enhanced team productivity
• Improved predictability in verification planning
• Faster adaptation to requirement changes

Orchestrating Success

The verification process is masterfully conducted through an integrated suite of management tools that work in concert. The combination of VRM, VIQ Regression Navigator, and VIQ Insight creates a synchronized verification environment where teams can collaborate effectively ensuring:

• Optimal resource allocation
• Automated workflow management
• Enhanced team collaboration
• Comprehensive result tracking

The transformation brought by Questa One unified coverage delivers measurable benefits:

• Earlier detection of coverage gaps
• Significantly reduced time to coverage closure
• Enhanced team productivity
• Improved predictability in verification planning
• Faster adaptation to requirement changes

Looking Ahead

By transforming verification from a collection of disparate tasks into a cohesive, intelligent process, Questa One unified coverage represents more than just a solution. It's a paradigm shift in chip design methodology. Teams can now collaborate more effectively, identify issues earlier, and achieve coverage goals with unprecedented efficiency.

The Future of Verification

This unified approach ensures verification teams not only meet today's challenges but are well-equipped for tomorrow's innovations. By combining systematic planning with intelligent assistance, Questa One unified coverage creates a verification environment that's more predictable, efficient, and ready for the next generation of chip design challenges.
