SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill eliminates the guesswork and steep learning curve of interpreting complex Vivado design analysis reports, diagnosing timing violations, and implementing effective timing closure strategies for FPGA projects.

Core Features & Use Cases

  • Comprehensive Report Interpretation: Covers all key Vivado analysis reports including report_timing, report_timing_summary, report_qor_assessment, report_design_analysis, report_utilization, report_cdc, report_drc, and report_bus_skew.
  • Structured Timing Closure Guidance: Provides decision trees for resolving setup and hold violations, congestion mitigation strategies, and QoR suggestion workflows.
  • Use Case: For example, if your Vivado implementation fails timing with a WNS of -2.5ns, use this skill to quickly identify whether the root cause is high logic levels, clock skew, missing constraints, or routing congestion, and apply the correct targeted fix.

Quick Start

Use the vivado-analysis skill to review your post-implementation timing summary report and list the top 3 recommended actions to close your current setup violations.

Frequently Asked Questions about vivado-analysis

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I interpret Vivado timing summary reports to diagnose setup violations?▼

To interpret Vivado timing summary reports for setup violations, analyze the Worst Negative Slack to identify whether the root cause is high logic levels, clock skew, missing constraints, or routing congestion, then apply the correct targeted fix.

What is QoR assessment in AMD FPGA implementations and when do I need it?▼

QoR assessment in AMD FPGA implementations evaluates design quality metrics to guide implementation strategy adjustments. You need it during timing signoff to validate constraint accuracy and detect congestion or timing closure issues.

How do I resolve CDC verification and DRC compliance issues in Vivado?▼

Resolve CDC verification and DRC compliance issues in Vivado by analyzing report_cdc and report_drc outputs to identify violations, then applying waiver management and design modifications to meet signoff requirements.

Can I use this analysis workflow for Vivado 2025.2 design complexity and congestion detection?▼

Yes, you can use this workflow for Vivado 2025.2 design complexity and congestion detection. It processes report_design_analysis outputs to evaluate routing congestion and suggest mitigation strategies for AMD FPGA implementations.

What's the best way to approach timing closure for hold violations in FPGA designs?▼

The best way to approach timing closure for hold violations is to use structured decision trees from report_timing analysis to diagnose clock skew and routing delays, then adjust implementation strategies accordingly.

Why does my Vivado implementation fail timing with negative WNS and how do I fix it?▼

Your Vivado implementation fails timing with negative WNS due to setup violations from high logic levels, clock skew, missing constraints, or routing congestion. Fix it by interpreting report_timing_summary to apply targeted implementation strategy adjustments.
