What problem does it solve?
Many multi-clock RTL designs suffer from undetected clock domain crossing (CDC) bugs such as missing synchronizers, improper multi-bit transfers, and reconvergence issues that lead to intermittent metastability and silicon failures. This Skill provides a structured, static-analysis-driven approach to detect those risks early and produce actionable remediation guidance.
Core Features & Use Cases
- Perform structural CDC analysis to map registers to clock domains and enumerate cross-domain signals.
- Verify synchronizer patterns (2-FF, 3-FF, gray-code, handshake, async FIFO) and flag Violations/Cautions with explanations and remediation steps.
- Generate human-readable CDC reports and SDC constraint files for signoff and downstream EDA tools; useful during pre-synthesis sign-off, new clock domain additions, or CDC checklist audits.
Quick Start
Run CDC verification on the top module to produce a CDC analysis report and corresponding SDC constraints.
