| description | Temporary fault injection to existing hardware is performed using only software without changing an implementation of the hardware. A fault injection interrupt process starts on an operation of a CPU using an interrupt that is not used by software, and an internal state of hardware is updated to the same value as a result obtained when a fault has occurred during the interrupt process. A clock of the CPU during the interrupt process is accelerated so that a period of time of the interrupt process is smaller than a period of time until a fault becomes effective. |
