Unformatted text preview: static hazard refers to the transient pulse on a signal line whose static value does not change. Depending on what the signal’s static value is, a static hazard may be a static 1-hazard or a static 0-hazard . A dynamic hazard , on the other hand, refers to the transient pulse during a 0-to-1 or 1-to-0 transition. Figure 3.21 illustrates the possible outputs of a network with hazards. In the figures, only one hazard pulse is shown, but in general there can be multiple pulses. The presence of hazards may cause a sequential network to malfunction. Following the above example, if the A B C E H J K 1 2 3 4 5 6 7 8 ± FIGURE 3.20 Static 0-hazard. static 1-hazard static 0-hazard dynamic 1-hazard dynamic 0-hazard ± FIGURE 3.21 Types of hazards....
