    Hello,

    I want detailed explanation about stuck-at fault method. I couldn't get the concept. I tried to learn on google. But I still don't get it.:eek: I know! I'm not good at grasping things.:( A help in this concept is greatly appreciated.:) I just need detailed explanation. If possible please give examples with explanations. Thanks in advance for your time.

    When your cell phone battery go low that a fault , Believe it or not your cell phone

    battery has memory.

    I just need to know the concepts single stuck-at fault and multiple Stuck-at fault. I couldn't understand how a fault is detected using this method. I'm a beginner.

    Or gate/ NAND gate. etc.. DRAM/SRAM

    If you let your phone battery discharge at certain rate all the time ,your battery

    will react to that as what you could call a fault. The battery will not last as long

    if you do not recharge it correctly.

    Systems are based on energy your battery needs to be recharged ,your body needs

    food to recharge.

    You are at a higher level on the fault chart , do you understand the binary system.

    What is your background , what level of studies do you have. What brings you to this

    question ,can you post a drawing of your question. If you do that more people will

    enter the post.

    It is used to represent a fault in a digital circuit when a pin is stuck at either logic high, low, or high impedance, despite any driving circuitry behind it.

    @loosewire I'm in final year of my UG in Elecronics and computer science. I need to give presentation on testing the Memories. Basically on DRAM and SRAM cells. But the basic of digital systems testing starts with Stuck-at fault methods which am unable to get it. I really appreciate you for your time to explain me this. Please guide me further.

    @tshuck Thank you very much for your reply. Can you please explain this with simple circuit with logic gates.

    How long is your presentation ,how big is your class your professor may not know as

    much you think. Know your class from past discussions ,study untill you are up to the

    part where you are stuck ,invite your professor to explain the question you are asking

    now. Call on a class mate to explain Tshucks, answer about the pins being stuck.

    Make a lecture how of what you want to learn, be ready to take notes if a class

    mate or professor knows more. In the mean time go back and do more studying.

    You will do two things ,learn to talk before your class on the part you know ,

    and study to learn more,you will have to do it some day. ( turning the page )

    If you have the curcuit ,keep going over it...know it well...

    Look your class in the eyes ,or look over them so they know you have confidence

    up to the part you are stuck on,then you have to be creative to get your professor

    involved so he will help you and the class. Check and see if a class mate know more than

    you without breaking rules. Remember this is the beginning of your career on public

    speaking ,it take a lot to do a resume someday.You are getting a head start in

    several ways ,think about it. If you give up on me ,what the class going to think.
