Hello everyone!
I came across the following problem. I have created a counter circuit in two different simulators. The circuit is the same in both cases, however I have noticed a difference when I started the simulation. In one of the sims the carry-out pin goes high immediately after the sim is started (power is applied), while in the other the opposite is true, the carry-out stays low when I start the sim.
Clock pulses are not coming in yet, the load input is tied low, and the up/down input (pin 10) is tied low too, since I want a down counter. Which simulator is right? Does the carry-out pin of the 4510 go high when power is applied or does it stay low?
