It seems you have two grouds: VSS1 and VSS2. If there is only PSUB, DRC will give a violation"pwell soft connected". you should add PSUB2 to isolate the two ground.
Re: Help!!!What is "pwell soft connected", a DRC e
From what I understand about soft connects, Both pwells should have diffusion with contacts given to supply individually. If one of them is not connected to supply using the proper layer, u might get this error.
Re: Help!!!What is "pwell soft connected", a DRC e
"Soft Connects" or "weak connects" usually refer to connections made on diffusions/wells or poly. If this error occurs, a connection on metal is expected by the DRC. I suspect you have a pwell connected to another pwell, but there is no direct metal connection between supply and the second pwell.
