How to Use the Converter
1. **Enter Formula:** Input your Boolean expression using standard operators (AND, OR, NOT) or symbols (·, +, -).
2. **Variables:** Ensure the comma-separated list of variables matches your formula (e.g., `A,B,C,D`). This is crucial for simulation.
3. **Conversion:** Select **NAND-only** (best for SOP forms) or **NOR-only** (best for POS forms).
4. **View Output:** The result card displays the **Original**, **Simplified**, and **Universal Gate** circuits. The universal gate is applied to the simplified version.
