1. A voltage margin controller located in a voltage domain and comprising:

  • monitoring branches including circuit function indicators configured to indicate whether circuitry in said voltage domain could operate at corresponding candidate reduced voltage levels; and

    a voltage margin adjuster coupled to said monitoring branches and configured to develop a voltage margin adjustment for a voltage regulator of said voltage domain based upon a comparison of an operating number of said circuit function indicators to a minimum passing threshold and a maximum passing threshold, wherein a value of said voltage margin adjustment is a total voltage drop of a lowest level passing branch of said monitoring branches that complies with said minimum and said maximum thresholds.
