Replace Prefix: MN   with   Prefix: X\n Prefix X is needed for subcircuits(.SUBCKT ..).\n4. OK\n5. Replace NMOS with FDB2532 on your transistor in the schematic.\n6. Put the model either in a file or on the schematic.\nAdd the line  \n    .include FDB32.mod\nif you use a model file. The model file should be in\nthe same folder as the schematic or in the ...\\sub\nfolder of the LTspice installation.
