Abstract
A power-supply control apparatus uses a margin setting unit to set the value of a margin that is added to a request voltage value VIDof an electronic device, which dynamically changes the operation voltage. A margin adding unit calculates a control voltage value VIDby adding the margin to the request voltage value VIDand outputs the control voltage value VIDto a power-supply apparatus. Therefore, the power-supply apparatus can supply a margin-included voltage value that is changed in accordance with a change in the operation voltage of the electronic device. Accordingly, it is possible to check the electronic device, which dynamically changes its operation voltage, by using a margin that is properly set.
