- *Solution*: Implement clock gating, power-aware synthesis, and proper heat sinking
I/O Configuration Errors
- *Pitfall*: Incorrect pin assignments causing signal integrity problems
- *Solution*: Follow manufacturer I/O banking rules and use proper termination
### Compatibility Issues with Other Components
Memory Interfaces
- Requires careful timing analysis with external DDR memory
- Compatibility with various memory standards (DDR2/DDR3) depends on specific configuration
Clock Distribution
- Sensitive to clock jitter from external oscillators
- Requires proper clock management circuitry for stable operation
Power Supply Sequencing
- Must follow specified power-up sequence to prevent latch-up
- Compatibility issues may arise with mixed-voltage systems
### PCB Layout Recommendations
Power Distribution
