Verilog-AMS Error in Virtuoso

[dshoter13]

Hi. I'm trying to simulate an ideal MOSFET in verilog-ams. After the code been written, save it under a verilog-ams cell viewn in Virtuoso, and them the symbol is automatically created. As soon as I instantiate the symbol in my Test Bench, when I try to run spectre (with verilog ams already defined) I get the following error: "input.scs" 43: I14 is an instance of an undefined model MOSFET
Any one has any idea how to solve it?

With best regards.
