IEEE 1801-2018, '''[https://standards.ieee.org/ieee/1801/6767/%|%Unified Power Format]''', is a Standard for design and verification of low-power, energy-eware electronic systems.  The standard specifies the commands that make up a Tcl script that describes the power intent of a system on chip.

** Description **

The power intent for each system is stored in a separate.  When subsystems are combined, the various power intents can be read, forming a single dataset that can then be used to verify the combined power intent.  A simulator is usually used to perform the verification.  Since a power intent is evaluated as a Tcl script in order to populate the combined dataset, '''Unified Power Language''' would have been a more apt name.
