18. An electronic device comprising:
at least one semiconductor functional circuit designed to perform a predetermined function;
a plurality of temperature sensors configured to detect a temperature of the functional circuit;
a throttling circuit configured to limit an operation of the functional circuit for a predetermined time amount when a first representative temperature calculated on the basis of first temperature signals respectively received from the plurality of temperature sensors is equal to or greater than a first threshold; and
an analysis unit configured to determine, when a second representative temperature calculated from second temperature signals received from the respective temperature sensors after lapse of the predetermined time amount is equal to or greater than a second threshold, whether a cause of heat generation is in at least one temperature sensor or in an environment around at least one temperature sensor on a basis of deviations of the second temperature signals.
