Switch in analogLib has Vopen and Vclose. I found this. Vopen must not be equal to Vclose. Otherwise, Spectre will announce an Error.
Then, I've done the following simulation. The schematic is below.
I don't see anything wrong (in fact your posts don't actually state what your issue is - you just show what you simulated and what the results are). Maybe if you look at my recent reply on the switch component that might help?
