rtl-equivalence-checker
Hardware verification tool for checking functional equivalence between two RTL designs (Verilog). Use when users need to: (1) Verify if two RTL versions are functionally equivalent, (2) Compare original vs. refactored RTL code, (3) Validate design changes or optimizations, (4) Identify semantic vs. cosmetic differences, (5) Generate counterexamples for non-equivalent designs. Analyzes interface alignment, state variables, logic differences, and produces detailed equivalence verdicts with plain language explanations. Particularly effective for design verification, code reviews, and regression testing of RTL modifications.

# RTL Equivalence Checker
Verify functional equivalence between two RTL designs with detailed analysis and counterexample generation.
## Overview
This skill compares two Verilog RTL designs to determine if they are functionally equivalent. It aligns interfaces and state variables, distinguishes semantic differences from cosmetic refactoring, and generates minimal counterexample traces when designs differ.
## Workflow
### 1. Basic Equivalence Check
Compare two RTL designs:
