Changes - Switch Model in PSpice is VSWITCH, it is not SW.
Second problem is with F device "Fmem" - here you can use a E device as controlling source. The change above is convert E device to V - however you need to make sure model intent is not altered. Change above does not gurantee that

Thank you very much for your reply. I need one more and last help. I am also getting error in the following code aswell. Please can you help me out with this.
