Hello! I'm new in layout design. I have a one problem. In the Fig.1 be see a post-layout simulation about my circuit. How we see, the ground not is in V=0V, is a random number. In the pictures, I put a original ground (gnd) (out of layout) and Vdd. In the other picture, I show a pull-down net about my circuit CMOS. In this print screen we will see any connections with ground, marked in yellow color.
