Cascading Logic Equations in a descending sequence
Cascading in a descending sequence means that the User utilizes the output signal of
“Logic Equation n+1” as input of “Logic Equation n”. If the output of “Logic Equation n
+1” changes, this change of the feed back signal at the input of “Logic Equation n” will
be delayed for one cycle.
