@Tim Edwards I am trying to pass lvs but there is pin match error its showing i checked my schematic and layout pins are correct could you please help me for this Also ii verified about SEL1 pin is extra it was not

In your

core.spice

layout netlist,

SEL1

appears in the pin list of the subcircuit but does not appear anywhere else inside the subcircuit. That leads me to conclude that

SEL1

is a floating label that is not attached to anything. That can happen if the label rectangle is not completely overlapping the metal that is it supposed to be connecting to.

@Tim Edwards THANK YOU
