Design of SAR adc using charge redistribution method

[Savankumar]

Hi team,
I was designing 4-bit SAR ADC in cadence.
While designing I am facing problems for connecting my 4-bit output to the 1-bit noConn.
Can anyone suggest me how I can connect it?
If I am connecting it simple way, I am getting the warning for short-circuiting and if I give a name to that connecting wire it shows the errors. For both cases, I am attaching a diagram here.
I will really thankful if anyone can help me out.

Two choices. Either property-edit the noConn to make its
instance name something like NX1<3:0> rather than a singlet,
or rip the bus (bus<3:0> -> bus<3>, bus<2>, bus<1>, bus<0>)
and place 4 noConn, one per tap.
