strange layout problem

i have designed an inverter (5 pmos, 2 nmos), and their gates connect together. but when i run calibre PEX, it says that, there are two gates not connected, floating gate, but i connect them together indeed, and LVS is OK. why? it is very strange, has anyone met this problem before? pls help me. thanks.

Re: strange layout problem

i connect them together indeed

Just together, not to a certain voltage level?

...or to a pin?

of course, i connect them to a voltage level, but there is the above problem, why?
