FAQPage Schema

How do I interpret Vivado report_timing_summary to identify setup violations?▼

Vivado report_timing_summary interpretation requires checking negative slack values and path types to identify setup violations. You analyze clock uncertainty components to pinpoint the exact timing failures.

What is timing convergence and how does it work in Vivado?▼

Timing convergence in Vivado is the iterative process of achieving positive slack across implementation phases. It involves interpreting QoR assessment data and applying optimization strategies across synthesis and routing.

How do I use report_qor_suggestions to drive timing convergence?▼

Use Vivado report_qor_suggestions to drive timing convergence by evaluating the generated optimization hints. You apply these suggestions to decide between constraint adjustments, retiming, or floorplan changes.

Can I use this guide for report_design_analysis and Rent analysis in Vivado 2025.2?▼

Yes, this guide applies to interpreting report_design_analysis and Rent analysis in Vivado 2025.2 workflows. It provides guidance on understanding connectivity complexity without executing TCL commands.

What is the best way to resolve CDC and DRC violations reported by Vivado?▼

The best way to resolve CDC and DRC violations is to carefully interpret report_cdc and report_drc outputs. You analyze the identified methodology issues to determine the correct corrective actions.
