## 2. Design Considerations
### Common Design Pitfalls and Solutions
Power Management Issues:
- Pitfall : Inadequate power supply sequencing leading to latch-up or device damage
- Solution : Implement proper power-on reset circuitry and follow manufacturer's power sequencing guidelines
Clock Distribution Problems:
- Pitfall : Poor clock tree synthesis causing timing violations
- Solution : Use dedicated global clock networks and follow clock management best practices
I/O Configuration Errors:
- Pitfall : Incorrect I/O standard assignments causing signal integrity issues
- Solution : Carefully configure I/O banks according to voltage requirements and signal standards
### Compatibility Issues with Other Components
Voltage Level Compatibility:
- The device supports multiple I/O standards (LVCMOS, LVTTL) but requires careful bank voltage assignment
- Mixed-voltage designs need level translators for interfaces operating at different voltage levels
Memory Interface Considerations:
- Limited embedded memory may require external memory components
- Ensure timing compatibility with external memory devices (SRAM, Flash)
Processor Integration:
- Can interface with various microprocessors and microcontrollers
- Pay attention to bus timing and protocol requirements when connecting to host processors
### PCB Layout Recommendations
Power Distribution:
- Use dedicated power planes for core (1.5V) and I/O (3.3V/2.5V/1.8V) supplies
- Implement proper decoupling with multiple capacitor values (0.1μF, 0.01μF, 10μF) placed close to power pins
Signal Integrity:
- Route critical signals (clocks, high-speed interfaces) with controlled impedance
- Maintain
