Patent ID: 7853844

Claim:
A semiconductor integrated circuit system comprising: a control target circuit configured to execute a program; a system information monitor unit configured to output system information indicating a state of the control target circuit; a circuit characteristic monitor unit configured to determine a circuit characteristic of the control target circuit and outputting the circuit characteristic as circuit characteristic information; a malfunction determination unit configured to determine whether or not the control target circuit is normally operating based on the system information; a reference circuit characteristic holding unit configured to hold the circuit characteristic information as reference circuit characteristic information when the control target circuit is normally operating; a malfunction factor determination unit configured to determine a malfunction factor based on the circuit characteristic information determined by the circuit characteristic monitor unit and on the reference circuit characteristic information when the control target circuit is not normally operating; a correction target determination unit configured to determine a correction target in the control target circuit based on the malfunction factor, generating objective electrical characteristic information for the correction target, and outputting the objective electrical characteristic information; and an electrical characteristic control unit configured to control the control target circuit in accordance with the objective electrical characteristic information.
