using *.cir files

In PROBE, FILE/OPEN/*.CIR, then choose the circuit of choice.

Then SIMULATION/RUN.

The *.CIR file MUST call all the needed libraries and subcircuits.

Myself, I prefer the methods described on the following pages of my website...

SUBCIRCUITS & SYMBOLS: SUBCKT.SLB

.cir files are just SPICE netlists. I can run them from the command shell with the SPICE supplied with the Pulsonix PCB software I use, perhaps you can do something similar with PSPICE.

Leon

Not precisely. *.cir files also contain commands, library calls, etc.

...Jim Thompson

I've come across SPICEs (SPICE OPUS is one) where that isn't the case, the netlist files have the cir extension and the commands etc. are entered separately.

Hello,

there is a big misunderstanding from the others about your .cir file. AD names their subcircuit model files with the extension .cir. I assume you use schematics for your circuit. Then you have to make a symbol for the subcircuit in .the .cir file. Therefore you have to master how to use subcircuits and how to to generate symbols for them. Have luck. ;-)

Best regards, Helmut

PS: I use LTspice.

Dear Helmut, Can I use devices other than Linear technology devices in LTspice.....? If yes how?....

Thanks............

There is a Linux version. 8-)

Yes!

As usual you have to learn a little bit. Do you know how a subcircuit is defined in SPICE? If yes then it's easy.

I have made an example with LTSpice with this AD588. It's on the "road" to you if your email is valid, if not then send me your email address. Maybe you tell me at least your first name or invent one.

Best regard, Helmut

You can learn a lot about LTspice in the Yahoo Group.

but

great.

Hello,

I forgot to tell that it's possible in LTspice to directly use SPICE-lines in a schematic. That means you have part of your circuit drawn and another part can be SPICE text lines. This allows you to use subcircuits without drawing a symbol.

X1 node1 node2 node3 ...... node16 AD588

The SPICE-line above connects the subcircuits to the nets node1, node2, .... node1, node2, ... are net names in your schematic.

Regardless of whether using symbols or text lines, you have to include the aubcircuit file.

.include mysubs.xyz

The file name can be any name recognized by MS-Windows.

Best regards, Helmut

Myself, I'm have symbolic preferences, where I can put down a symbol for the subcircuit and probe its pins... described on the following pages of my website...

This is very handy when you are designing only one section of a chip (or PCB) and must interface to other people's work.
