## 2. Design Considerations (35% of content)
### Common Design Pitfalls and Solutions
Power Management Issues
- Pitfall : Simultaneous switching noise during mode transitions
- Solution : Implement staggered power sequencing with 1ms delays between core and I/O power-up
Clock Distribution Problems
- Pitfall : Jitter accumulation in daisy-chained clock networks
- Solution : Use dedicated clock buffers and maintain impedance-controlled routing
Thermal Management
- Pitfall : Inadequate heat dissipation during sustained maximum performance
- Solution : Incorporate thermal vias under package and consider active cooling for Tj > 85°C
### Compatibility Issues
Memory Interface
- Issue : Timing mismatches with DDR3L memory controllers
- Resolution : Use manufacturer-recommended termination schemes and length-matched routing
Analog Front-End Integration
- Challenge : Ground bounce with high-resolution ADCs
- Mitigation : Implement split ground planes with controlled connection points
Power Supply Sequencing
- Critical : Core voltage (1.2V) must stabilize before I/O voltage (3.3V)
- Implementation : Use power management ICs with programmable sequencing
### PCB Layout Recommendations
Power Distribution Network
- Use 4-layer minimum stackup: Signal-GND-Power-Signal
- Place decoupling capacitors within 3mm of power pins
- Implement separate power planes for analog and digital sections
Signal Integrity
- Maintain 50Ω single-ended impedance for high-speed interfaces
- Route critical clocks as differential pairs (100Ω differential)
- Keep high-speed traces >5x substrate height from board edges
Thermal Design
- Provide 25mm² copper pour under package for heat spreading
- Use thermal vias with 0.3
