This I see as part of a Power Mosfet:

General form: m[name] [drain] [gate] [source] [substrate] [model]

.model [modelname] [nmos or pmos] ( [parmtr1=x] . . . )

Example: m1 2 3 0 0 mod1
m5 5 6 0 0 mod4
.model mod1 pmos
.model mod4 nmos ( vto=1 )

My question is after the m1 are numbers to which those refer?
is any number fine?
Please use a real datasheet from a manufacturer to produce a spice model.

The numbers "2 3 0 0" are nodes. The order of the nodes is important. The names of the nodes are generally not important; but it can be helpful if they are meaningful names.

 

To perhaps further clarify, the nodes are connection points in the circuit. Thus all nodes of the same number are connected together. In Spice, node 0 is always common (ground).
