Hazard analysis in CLC via time dependant logic variables

-The present paper considers the problem of hazard in combinatorial logic structures. We shall define an improvement for the time constants method, improvement that will consider, among other features, the specific function implemented by the gates used (we are mostly interested by the inverting characteristic). In this endeavor we shall define a new type of operator and a new type of variable, both of them applicable when propagating the switching times for a specific circuit. The time constants method is a very laborious one (considers all the possibilities disregarding the specific function implemented by a circuit). We shall prove that only a strictly limited number of situations should be considered –in conjunction with the function that is being implemented by the circuit analyzed. In order to achieve this goal we shall express the logic function with respect to a new logic variable that is time dependent. Operations with this new variable prove to have some very interesting properties (shown in the paper) that will allow us to restrain the window of possibilities for hazardous functioning to a very narrow one.
