Help! Cadence spectre error message for TSMC MM 0.18 PDK

[Analogworld]

Someone has posted this topic before, but no one ever provided a solution to solve this issue. I am now having the same situation that Spectre can not find the transistor model in the correctly pointed tsmcrf library. I am sure that the require Spectre model file is correctly pointed, and it works fine for the other devices (i.e. well or poly resistors) in the same file location.

Did anyone exprience this problem before? Please help

Thanks for note Ashi! However the problem is not about how to aviod pointing to the location of the models when you simulating the circuit each time.

The problem is that this error message appeared even when the correct model is pointed. The simulation is not even running! It only works for the resistor models but just not the transistor models.

I looked into the pointed model file "rf018.scs" that provided by TSMC's cadence design kit. However, the transistor model named "nmos2v" (as shown in the error message), doesn't even exsit in the Spectre model file! And Cadence do not let me change the transistor's model name from the property menu.

Is there a problem with the TSMA's Cadence design kit? I doubt it though! Then how should I get it to work? Any help would be greatly appreciated.

Did you use the cell in the library of TSMC'S PDK.The model name of transistor in pdk is permanent.If you use the cell in the library of TSMC's PDK and the PDK is provided by TSMC,you need ask them why the model name in model file is wrong.
