TEXT -472 488 Left 0 ;1. Add a "nmos" component to the schematic.\n2. Move the cursor over nmos-transistor and \n then press <Ctrl>+ the right mouse button.\n3. Replace Prefix: MN   with   Prefix: X\n Prefix X is needed for subcircuits(.SUBCKT ..).\n4. OK\n5. Replace NMOS with 2N7002 on your transistor in the schematic.\n6. Put the model either in a file or on the schematic.\nAdd the line  \n    .include modelfile  \nif you use a model file. The model file should be in\nthe same folder as the schematic.
