## 2. Design Considerations (35%)
### Common Design Pitfalls and Solutions
Pitfall 1: Inadequate Power Supply Decoupling
- Problem : Signal integrity issues and random logic errors
- Solution : Implement recommended decoupling network with 0.1μF ceramic capacitors placed within 5mm of each power pin
Pitfall 2: Poor Clock Distribution
- Problem : Timing violations and metastability
- Solution : Use dedicated clock routing resources and implement proper clock domain crossing synchronization
Pitfall 3: Insufficient I/O Planning
- Problem : Signal integrity degradation and EMI issues
- Solution : Follow manufacturer's I/O banking rules and implement proper termination
### Compatibility Issues
Power Supply Compatibility:
- Requires precisely regulated 3.3V and 1.2V power rails
- Incompatible with 5V TTL logic without level shifters
- Sensitive to power sequencing violations
Interface Compatibility:
- LVCMOS 3.3V I/O standards compatible with most modern digital components
- Limited drive strength for high-capacitance loads
- Requires external buffers for driving multiple devices or long traces
### PCB Layout Recommendations
Power Distribution:
- Use separate power planes for core (1.2V) and I/O (3.3V) supplies
- Implement star-point grounding near the device
- Ensure adequate copper thickness for current carrying capacity
Signal Routing:
- Route critical signals (clocks, high-speed interfaces) first
- Maintain consistent impedance for differential pairs
- Keep high-speed traces away from noisy power supplies
Thermal Management:
- Provide adequate copper pour for heat dissipation
- Consider thermal vias under the package for improved heat transfer
- Allow sufficient clearance for potential heatsink installation
