    摘要: A chip damage detection device is provided that includes at least one bi-stable circuit having a first conductive line passing through an observed area of a semiconductor integrated circuit chip for damage monitoring of the observed area. The at least one bi-stable circuit is arranged to flip from a first stable state into a second stable state when a potential difference between a first end and a second end of the first conductive line changes or when a leakage current overdrives a state keeping current at the first conductive line. Further, a semiconductor integrated circuit device that includes the chip damage detection device and a safety critical system that includes the semiconductor integrated circuit device or the chip damage detection circuit is provided.

    摘要: A differential communication bus comprising a master module and a plurality of slave modules connected to at least first and second conductors whereby to communicate between the master and slave modules. The master module comprises a driver for applying first and second voltages respectively to the first and second conductors and for sourcing and sinking currents in the first and second conductors. The driver controls a difference between the first and second voltages and a common mode value of the first and second voltages. The driver includes first sourcing and sinking current limiters and second sourcing and sinking current limiters for limiting the currents in the first and second conductors. The master module is selectively responsive to a fault condition triggering simultaneous activation of the first and second sourcing current limiters or of the first and second sinking current limiters to disable the driver.
