Methods of removing single variable static hazards in Boolean functions

Two methods are presented in this paper for removing single variable static hazards in Boolean Functions. The first method is a hand calculation method that uses a single variable static hazard cover algorithm. The hand calculation method can be used in the classroom and does not require computer assistance. The second method involves using a single variable static hazard cover software synthesis tool. The second method is more convenient to use outside the classroom on a PC that is available for engineering student use or perhaps on personal computers. To illustrate the process of obtaining single variable static hazard covers, the standard Karnaugh map approach is also used. A commercially available design synthesis tool and schematic capture/simulation timing tool are also used in this paper
