1. A method comprising:
embedding a software-controlled load at an output of a point of load (POL) in parallel to a load that receives power from the POL;
applying a small incremental load to the POL using the software-controlled load;
measuring a transient response of the POL to the small incremental load using an embedded analysis functionality; and
determining a health condition associated with the POL based on the transient response.
