Hazard algebra

Normally the frequency divider designed by Boole algebra and to design a frequency divider with any divide factor, we have to repeat all over again every design step as the same. So to avoid of wasting time and money, instead of using traditional Boole algebra in digital technical we replace it by mathematical models in high algebra. And because of that we can design frequency dividers use computer. 1. Modeling of function circuit

There are many methods to design digital circuits without hazard, such as the use of Boolean algebra, algebra hazard, karnaugh map, matrix method, VHDL, etc. However, these methods are not very suitable for the design of circuit system such as design of GALS circuits. In this case, synchronization is the most optimal method. 1. Introduction Hazard is the essence of digital circuits including synchronous circuit and asynchronous circuit. Hazard occurs as much as “autumn’s leaves” [1] and has adverse impact on the working of digital circuits. ...

Under the name of ideal circuit network, it is easy to make us understand that digital circuits are independent of the inner status and their outputs just only depend on the inputs. They are time constants and therefore Boolean algebra is a special suitable means of describing. In fact propagation delay time of circuit system should be in thought firstly in designing circuit network. In that case Boolean algebra does not seems to be fully suitable for describing actual circuit systems.
