## 2. Design Considerations
### Common Design Pitfalls and Solutions
Power Supply Issues
- Pitfall : Inadequate decoupling causing signal integrity problems
- Solution : Implement multi-stage decoupling with 0.1μF, 0.01μF, and 1μF capacitors
- Implementation : Place decoupling capacitors within 2mm of power pins
Timing Violations
- Pitfall : Ignoring pipeline latency in timing calculations
- Solution : Account for 2-cycle read latency in system timing
- Implementation : Use manufacturer's timing models for simulation
Signal Integrity Problems
- Pitfall : Excessive trace lengths causing signal degradation
- Solution : Maintain controlled impedance and proper termination
- Implementation : Keep critical signals under 2 inches in length
### Compatibility Issues with Other Components
Voltage Level Compatibility
- Issue : 1.8V I/O may not interface directly with 3.3V components
- Solution : Use level translators or series resistors for mixed-voltage systems
- Recommendation : Texas Instruments SN74LVC8T245 level-shifting buffer
Timing Synchronization
- Issue : Clock domain crossing with asynchronous systems
- Solution : Implement proper synchronization circuits
- Recommendation : Use dual-port synchronizers for clock domain transitions
Bus Loading
- Issue : Excessive capacitive loading on
