| Aug 19, 2021 at 17:29 | comment | added | jay | Well, I had to remove my answer, thought it was good (and truth) but did not entertain people, I guess. Once I was deep in Ternary logic, and I understand what you are doing. But do not understand why you are doing so. I am curious to ...D.. Would you please share the reasoning behind? | |

| Aug 19, 2021 at 16:46 | comment | added | glen_geek | what would happen when fixed connections result in an unsatisfiable condition... a ring oscillator comes to mind (a loop of an odd-number of inverters). Because of propagation delay, and finite rise/fall time, it oscillates. However, signal flow is in one direction only, not as your initial proposition. | |

Any "real" input would override the signal. Forcing the output to high and one of the inputs low will cause the gate to output low (since it's a normal gate) but since the output is also being forced high some part will overheat. | |
