Static hazards, how to detect them?
Static hazards occur not when there are adjacent 1s or adjacent 0s on the k-map but when there are non-interlinked adjacent circled groups on the k-map (adjacent diagonally is ok). So the procedure is to circle the groups of 1s if you are deriving an expression for F or circle the groups of 0s if you are deriving an expression for F'. Then look to see if there are any groups which are adjacent but not overlapping. To eliminate a hazard you must add an extra grouping circle which overlaps both of the adjacent non-overlapping groups.

If a logic circuit has no static hazards then there will be no static hazards irrespective of gate delays in the circuit. Try drawing a simple circuit which has no hazards. Now add two series not gates at various points in the circuit and see what the output does for all the possible input state changes to see if there are any glitches at the output.
