failed counter

01:23:56

I tried to make a simple counter (counting 0-9 and R repeating it) using an oscillator designed by me ( I dint wanted to use the sinewave generator in the app) but it keeps failing for some reason someone please take a look at this and try to give me an solution

Best to keep it simple here. I had to flip the second diode after the and gate to get this to work, then it freaked out once it got to A(probably because then the and gate triggered and had two sources on the transitor). The best thing to do for the sim is to use a logic train, and hook that up to your up counter. Then hook up an and gate with the inputs on a and d of the counter and the out put on the reset pin.

Yes the same thing is happening to me after i got to A or 1010 (binary value) it freaks out completely and the whole thing crashes

Really? Cause I have a few counter circuits on here and they count from 0-9 just fine...

The output of your AND gate should be connected to the reset pin on your counter and not the UP pin.
