In Virtuoso, what to do with the pins of the devices which are not used?

[giorgi3092]

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

There is a noConn symbol down in the "basic" library,
which will "fix" the SRC complaints.

That was quick, thank you!
