FPGAs and adaptive SoCs are powerful compute devices that are capable of many applications. Power sequencing is an important requirement for all AMD devices that is often overlooked or implemented incorrectly. It is important to implement power sequencing early in the design to avoid pitfalls. Power delivery rail consolidation is also critical in determining what level of power savings are possible via power management. Static saving by turning off complete domains is only possible when implementing the full power management consolidation. From dedicated ICs to Versal device integrated power sequencing methods, there are multiple ways to implement power sequencing and each method has different merits and optimizations. Properly sequencing power improves system reliability and avoids unexpected issues.
