ERROR (SFE-23): "input.scs" 14: N0 is an instance of an undefined model nmos. Tried by adding simulator lang=spice in the first line of the model file

Hello everyone, 

I am new to cadence I am trying to simulate a basic inverter circuit using spectre but I am getting this error

ERROR (SFE-23): "input.scs" 14: N0 is an instance of an undefined model nmos. I saw several posts regarding the same problem I but none of those posts helped me, I already attached a model library file to it which is in spice format with extension .m and also tried by adding simulator lang=spice in the first line of the model file but I am getting the same error. I also tried by changing the extension to .scs and changing lang=spectre, however, I am getting a new error after this step. previously I did a simulation with tsmc13rf technology and model file written in spectre which worked perfect but I don't know why it was not working when I am trying to simulate spice model files (I got these from NSCU CDK beta version ) 

I am also attaching my netlist file and few lines of model library which I am using 

simulator lang=spice
.model NMOS_VTL nmos level = 54
+binunit = 1 paramchk= 1 mobmod = 0
+capmod = 2 igcmod = 1 igbmod = 1 geomod = 1
