Abstract:
1. A design structure embodied in a machine-readable medium used in a design process, the design structure including a system for detecting a fault in a signal transmission path, the system comprising: a hysteresis comparator including a latch having n-type field effect transistor (“NFET”) storage elements, said hysteresis comparator being operable to detect a crossing of a reference voltage level by an input signal arriving from said 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; wherein the design structure includes a netlist which describes the system; and wherein said hysteresis comparator further includes p-type field effect transistor (“PFET”) pull-up devices connected in current-mirroring relation to pull-up devices connected to complementary nodes of said latch.
