To optimize your FPGA design for timing closure using the Intel Quartus Prime Pro Edition software, you can follow the three key steps outlined in the "AN 903 Accelerating Timing Closure" user guide:
1. **Step 1: Analyze and Optimize RTL:**
- Correct Design Assistant Violations: Identify and correct basic design rule violations.
- Reduce Logic Levels: Ensure all design elements receive the same Fitter optimizations.
- Reduce High Fan-Out Nets: Minimize resource congestion and simplify timing closure.
2. **Step 2: Apply Compiler Optimization:**
- Apply Compiler Optimization Modes and Strategies: Specify primary optimization mode goals for design synthesis.
- Reduce Congestion for High Utilization: Experiment with Area and Routability options to reduce congestion.
3. **Step 3: Preserve Satisfactory Results:**
- Lock Down Clocks, RAMs, and DSPs: Back-annotate satisfactory compilation results to ensure consistent placement of large blocks.
- Preserve Design Partition Results: Focus optimization on specific design blocks by preserving successful partitions.
By following these steps and utilizing the detailed guidelines provided in the user guide, you can effectively accelerate timing closure in your FPGA design using the Intel Quartus Prime Pro Edition software.
