Abstract
A semiconductor integrated circuit includes a circuit block connected to an arithmetic processing unit via a bus, a power supply noise data generator which is configured to generate a power supply noise data signal by converting power supply noise generated in power supply voltage of power supply operates the circuit block, an error detector which is configured to detect an error of data outputted from the circuit block to the bus, and a write controller which is configured to associate power supply noise information based on the power supply noise data signal with data on the bus and write the data in a storage unit, and to stop to write the data in response to the detection of the error by the error detector.
