YMMV depending on the SPICE simulator you use.

For instance, Linear's free LTSPICE defines things slightly differently to,
say,
PSPICE- the voltage level established as a "1" in PSPICE and the voltage
level of a "1" in LTSPICE are not the same, so a model designed for one
will only sometimes only kind of work with the other.  They can be
converted,
with time and effort, but it's something to be aware of.
