in some cases, actually provide an indirect path for E-hazard formation, thereby making
E-hazard formation possible whereas otherwise it would not be. E-hazards are potential
defects in the sense that the FSM logic is not “born” with these defects as can be the case
for static hazards. E-hazards require explicitly located path delays of magnitude exceeding
the minimum requirements before they can form. However, an active E-hazard is guaranteed
to cause malfunction of the FSM, whereas active static hazards in the NS logic may or may
not be disruptive to the operation of the FSM. Before a static hazard in the NS-forming logic
can cause malfunction, it must be “strong” enough to cross the switching ...
