At this point, you must evaluate the constraints. If power is too high, try the following:
- Reduce power in the design. This approach is the least costly in terms of time. For information, see this link in the Vivado Design Suite User Guide: Power Analysis and Optimization (UG907).
- Improve the thermal solution within the thermal design constraints. For example, change the heat sink composition to improve the thermal solution, such as adding heat pipes or forced air.
- Improve the board and thermal solution, if possible. However, be aware that thermal changes might increase the power in the design.
- Reduce the complexity or features in the design. Use this approach as a last resort. For example, you can reduce power by reducing clock frequencies, resources used, or toggle rate. You can use XPE for “what if” analysis to quickly estimate the impact of design changes.
