Re: hazards

Your mean is Stuck at fault or not ?
"stuck at 1 " means the net is kept high level.
"stuck at 0" means the net is kept low level

Re: hazards

Hazards is referring to the wrong logic value being propogated along a gate due to difference (may call it skew) in the arrival of inputs to the Logic Gate

a 0 or 1 Hazard and a glitch are essentially same

hazards

is cause for the glitch is same as for hazards.wat is the output voltage levels when glitch occurs.will it be good 1 or 0

Added after 12 minutes:

i think glitch occurs due to more switching activity?isn't it?
