Thanks, I've ironed out the issues and submitted the project.

Ok, i found the gate that triggers the problem, it is the XOR that gets input from the counter stop logic, and outputs into the JK flip flops.
But how can i workaround this problem. I'm beyond confused.

Here I simplified it for you. Look at "Counter 0 simple" and "Counter 1 simplified". Weird, it says its from another version and won't open. I really don't know whats going on with the Oscillation error, if you can help point me in the right direction, i tried all sorts of wirin...

Hello Again,

Here are two counters separated into their respective logic circuits, and the same goes for the others, they work individually, but the problem arises when i attempt to connect them together (the Oscillation error above).

Thanks

First the expression x XOR 1 is equal to NOT x. So, I don't know what you are trying to do here. Second it is very hard to understand your circuit as it is so big. If you move the repeated parts to separate circuits it will be much easier to test and find issues, not to mention to look at your diag...

Ok, I found that the problem is with the XORs that are connected with the high pulse (1), but im not sure how to mitigate and circumvent the problem, because these XORs are crucial to the logic that stops the counter (putting the J and K to a hold state of 00) . Sorry for the many requests, but i re...

Hello

Is there a file i can import from that has the decoder with an enable bit, i need it to strobe an Asynchronous BCD counter otherwise it skips random numbers.

Thanks,
Alan

Hi Alan, JK flip-flops are flipping to a random state at power on. That is why you see it starting at the random state. You will need to reset them at power on. Please read this discussion: https://logiccircuit.org/forum/viewtopic.php?t=3 and especially the last suggestion from ehennig. On the othe...

BCD counter outputs some undefined behavior. It should count from 0000-9999, but it starts at a random value (eg. 2304), whereas im sure it will work.
Im at my wits end.
Thanks
