oh sorry, i forget to tell what is ploblem. when i start the simulation 7segment just have 0-3-0-3-0-3 it should be 0-3-1-4-2-5 i don't know whyThanks for showing some work. It's appreciated.
But it would sure be helpful to get a better description of what it is doing wrong beyond "isn't work".
What, specifically, IS it doing that it isn't supposed to be doing?
What steps have you taken to debug the design?
Have you checked to see if the behavior is or is not consistent with the schematic?
Have you measured the values on the various nodes when it is misbehaving and determined which, if any, aren't at the values they should be?
So, it goes from 0 to 3 just fine. But it is going from 3 to 0 instead of 3 to 1.oh sorry, i forget to tell what is ploblem. when i start the simulation 7segment just have 0-3-0-3-0-3 it should be 0-3-1-4-2-5 i don't know why
Thanks. That makes it "homework", which is a catch all for any assigned work whose primary purpose is for you to learn something or to demonstrate that you have learned something.Up-down counter project in Digital course.
i have rework in the simulation but it is working the same before.So, it goes from 0 to 3 just fine. But it is going from 3 to 0 instead of 3 to 1.
That means that the next state that it SHOULD be going to is 0001 and the state that it IS going to is 0000.
Does that not suggest some place that you might start your investigation?
Does it? Seems like they have also give you a strong hint on where to look. What have YOU done to try to determine if that is where the problem is? We've already identified an operating state where it misbehaves. YOU need to examine the value of all the logic in that state that could be causing the observed wrong behavior. So do that and show us what you find.My professor said my project has one mistake on switch SPDT.
I have no idea what you mean by this. The correctness of your solution has nothing to do with drawing your schematic so that it is clean and presentable.i just follow my solution, is it wrong?
