## 2. Design Considerations
### 2.1 Common Design Pitfalls and Solutions
#### Pitfall 1: Insufficient Power Supply Decoupling
Problem : Inadequate decoupling causes voltage droops during high computational loads, leading to processor resets or data corruption.
Solution :
- Implement multi-stage decoupling with 100nF ceramic capacitors placed within 5mm of each power pin
- Use bulk capacitors (10-100μF) at power entry points
- Follow manufacturer's recommended decoupling network for core and I/O supplies
#### Pitfall 2: Clock Signal Integrity Issues
Problem : Jitter in clock signals degrades ADC/DAC performance and timing margins.
Solution :
- Use dedicated clock generator ICs with low phase noise (<1 ps RMS jitter)
- Implement proper termination for clock traces (series termination preferred)
- Maintain continuous ground plane beneath clock routing
#### Pitfall 3: Thermal Management Oversight
Problem : Inadequate heat dissipation leads to thermal throttling or premature component failure.
Solution :
- Calculate worst-case power dissipation using manufacturer's power estimation tools
- Implement thermal vias under the package connecting to internal ground planes
- Consider active cooling solutions for sustained high-performance operation
### 2.2 Compatibility Issues with Other Components
#### Memory Interface Compatibility:
- DDR3 Memory : Requires careful timing analysis; use manufacturer-provided memory controller configuration
- Flash Memory : Compatible with SPI NOR flash up to 133 MHz; verify command sequence compatibility
#### Analog Front-End Integration:
- ADCs : Optimal performance with 16-bit SAR ADCs sampling at 1-
