Static-1 Hazard
A static-1 hazard is a set of two input combinations Xa and Xb
(i) Xa and Xb differ in only one input variable;
(ii) both Xa and Xb produce a 1 output;
but it is possible for a momentary 0 to appear in the
output when the input transits from Xa to Xb or from
i.e., a static-1 hazard is a possibility of a 0 glitch when
we expect a steady 1 output.
