Hi,

I built this little 4-bit T-flip-flop counter and I really don't need the Qbar outputs from the flip flops. However, I can't just leave them unconnected because of the warnings.

What is the practice with such pins when designing circuits? I presume I would have to make them not-connected (NC). But I don't know how it works in Virtuoso. Can anyone clarify this?

Thanks,
Giorgi
