Hello, Mohamad,
INC files are included as lines in the SPICE file. In other words, the
entire INC file replaces the one INC line. The file extension is typically
inc or mod, as in "include1.inc" or "include2.mod". The LIB statement works
the same way; model library files often have an extension of .lib.
The other extensions you list apply to SPICE netlist files. A tool's
"standard" extension can be left off when sending the file to simulation.
As you noted, one can use "hspice x.sp" or "hspice x" with the same results.
Other SPICE flavors use .cir, .spc, or other extensions in the same way.
If one uses a personal preferred extension, such as cir, with a tool such as
HSPICE,, the only requirement is to submit it with the full file name, such
as "hspice x.cir". (Of course, one should also double-check that the model
parameters and parameter names are correct for the selected simulator.)
"Model" is used for many things. A "macromodel" is a model built from other
components. Also, "model" can refer to an "element" provided with the
simulator, or the parameters and equations that define that model, or the
parameter values for a specific component. Circuit designers sometimes call
a circuit netlist a model. (NOTE: model parameters and parameter values are
generally NOT portable between SPICE flavors.)
Regards,
Lynne

Hi all
I have many files that are called Spice model files,*.sp

Thanks and Regards
