摘要： A design structure embodied in a machine-readable medium used in a design process may include a system for detecting a fault in a signal transmission path. Such system may include, for example, a hysteresis comparator including a latch having n-type field effect transistor (“NFET”) storage elements. The hysteresis comparator may be operable to detect a crossing of a reference voltage level by an input signal arriving from the signal transmission path such that when the comparator does not detect an expected crossing of the reference voltage level by the input signal, the fault is determined to be detected in the signal transmission path.

摘要： In a method for performing equalization of a communication system, a predetermined signal can be transmitted from a transmitter unit to a receiver unit in a downchannel direction on a transmission line, for example as a pair of differential signals which simultaneously transition in opposite directions on respective signal conductors of the transmission line. At the receiver unit, an eye opening of the signal received from the transmission line can be analyzed to determine equalization information. Equalization information can be transmitted from the receiver unit to the transmitter unit in an upchannel direction on the transmission line and be received at the transmitter unit. Using received equalization information, a transmission characteristic of the transmitter unit can be adjusted.

摘要： A system is provided for detecting a fault in a signal transmission path. In one embodiment, the system can include a variable amplitude signal attenuator which is operable to modify an input signal by variably attenuating a signal voltage swing of the input signal. Desirably, the input signal is attenuated only when transitioning from a high signal voltage level towards a low signal voltage level d variably, such that a larger high-to-low signal voltage swing is attenuated more than a smaller high-to-low signal voltage swing. Desirably, a comparator, which may apply hysteresis to the output signals, may detect a crossing of a reference voltage level by the modified input signal. In this way, when the comparator does not detect an expected crossing of the reference voltage level by the modified input signal, a determination can be made that a fault exists in the signal transmission path.
