  • Microcontroller and method for modifying a transmission signal
    Patent number: 11080158
    Abstract: A microcontroller includes a signal interface for transmitting signals. The microcontroller further includes an error injection module. The error injection module is configured to tap a transmission signal associated with the signal interface. The error injection module includes a synchronization unit. The synchronization unit is configured to detect within the tapped transmission signal an occurrence of a synchronization event. Further, the error injection module is configured to modify the tapped transmission signal by adding at least one disturbance to the transmission signal in synchronization with at least the detected occurrence of the synchronization event.
    Type: Grant

  • Microcontroller and method for testing a microcontroller
    Patent number: 10444281
    Abstract: A microcontroller includes a data memory configured to store test signal data. The microcontroller further includes a signal generator configured to process the test signal data in order to provide at least one test signal. The microcontroller also includes a circuit under test configured to process the test signal. The test signal data includes at least one pattern snippet and an associated pattern descriptor. The pattern snippet includes data concerning a content of a part of the test signal. The associated pattern descriptor includes data concerning a pattern formed by the pattern snippet within the test signal.
