The Xilinx® Power Estimator (XPE) spreadsheet is a power estimation tool typically used in the pre-design and pre-implementation phases of a project. XPE assists with architecture evaluation and device selection and helps in selecting the appropriate power supply and thermal management components that may be required for your application. The XPE interface lets you specify design resource usage, activity rates, I/O loading, and many other factors which XPE then combines with the device models to calculate the estimated power distribution.
XPE is also commonly used later in the design cycle during implementation and power closure to, for example, evaluate power implications of engineering change orders (ECO). For large designs implemented by multiple teams, the project leader can use XPE to import usage and activity for each team's module, then monitor the total power and reallocate the power budget to ensure constraints are met. For more information on using the Xilinx Power Estimator, see Xilinx Power Estimator User Guide (UG440) and Xilinx Power Estimator User Guide for Versal ACAP (UG1275).
