LM317 Netlist To Device??

Guest
Greetings,

I'm having more than a problem creating this device, LM317, in
CircuitMaker. When I load the "lm317.net" file into CM, I get this
message: "No Spice Analysis Specified in: lm317.net". OK, so I pull up
the spice data help screen and now I'm totally confused. I gathered
that the " % " sign preceeds the designations but, how do I define it
as a device?

This is my first attempt at creating a device from a netlist so any
guidance in this matter will go a long way in restoring my battered
ego;-)

I've included the LM317 Netlist for examination:

Randy:

for an example, look in C:\CM06\Models\MCEREGS.LIB

There is already an LM317 which looks identical to the one you are
trying to create.

I don't know a lot about CM, but a netlist is the spice netlist, not a
model .subckt specification. You are obviously loading in what CM thinks
is a complete spice netlist that has a full run specified in it. You
need to look at the documentation to find out how to add an actual
*model*. Your problem is that you don't yet know what is what in spice.
A spice netlist tells spice how the circuit is constructed and what to
do with it. A model is a only *part* of a final netlist.

The convention for files with models are .lib, .mod, .sub. The
conventions for spice netlists are .cir and .net.

If it were SuperSpice, it would be a no-brainier. Just drag drop a
model.lib to the main window. The model will show up in the docked list
on the left. When you place it is will pop up a dialog allowing you to
chose an existing symbol to attach to it, if it cant figure it out
itself.

I'm not clear what you are trying to do. Is this possibly a learning
exercise, trying to create a model from scratch, but deliberately
choosing a model that already exists so that you can check the result?
You don't say which version, but from your other thread I assume
you're using CM 6. As Robert has said, the CM 6 library already
contains an LM317, and it has the spec you have listed. But, as
already pointed out, that is the 'model subcircuit data', not the
'netlist'.

Yes Terry, this is/was a learning exercise. I found the LM317 in the
..lib file and incorporated it however, I did'nt learn anything about
creating a model from scratch. There are two other devices in the
LM317/LM301A regulator circuit (found in the LM317 datasheet) that CM6
does not have a model of I could find in the LIBs':

MJ4502 Transistor, 200W, 100V, 30A, TO-3
and
IN457 Diode (no data yet)

If I had a walk-thru on this first attempt, I would understand the
process. The CM6 help files are a little confusing without an example.
