New component for simulation

[Alis]

Hello,

I'm having some trouble to get my new component to simulate.

It's a photoMOS and I downloaded some data for a this component from the develpers homepage.

But I don't know much about Pspice so I'm pretty lost how to insert it into the component.

The first thing I did was to cut out the data for only one component (the .lib-file felt like it was made for a lot of different components). Then I tried to make a component in Multisim by using "component wizard". Then I inserted my "new" file (AQY21S.lib) during some step.

The scematic and PCB symbol works fine. But when I start to simulate I get some errors (and the simulation never starts).

Could anyone expalin for me how to insert a SPICE file from a manufactor for simulation. What in the file is needed and how to insert it in a component. Or if someone could point out a good tutorial for a newbe in Spice.

I also attach 2 files, ps_aqv21s.zip is the original from the manufactor and AQY21S.zip is my try attempt to cut out only one component fromit.

Thankful for help

Pspice is not fully supported in Multisim, Spice is supported. Anyways, the models RES and CAP had to be changed to R and C respectively. I am not sure how to make a simulation of your circuit, however, after changing these parameters I did not got any error when trying to simulate only that component by itself... it just asked for a GND signal. Try this model:

Hello,

I’m still having some trouble to get my component to start working correctly in MultiSim.

I have cut out some lines in to make it smaller and easier to find the problem, see the attached file.

As it is now, the first diod will work, but not the second and third. If  I change name on LEDA to LED it will work. WHY?!?

Can’t I use any name I want here?

This is what the SPICE “spec” says (from a book on internet):

.MODEL MODName D (IS= N= Rs= CJO= Tt= BV= IBV=)

I try the component by placing only the component on a schematic and then chose “Transfer -> Export to netlist” and then open this netlist. The I get the errors in a external window.

Could anyone explain to my why I can’t use any word I like there, and how to make it work.

Have you tried leaving a space between LED and A?... "LED A"... instead of "LEDA", did you tried the code I placed here before? Did it worked?

[Alis]

Thank's for your replay Nestor,

Yes I tried your code, and that brought me one step future. But it still won't work.

With your code I still get a lot of faults. If you just make a circuit with a component wich have your code, and then export it (“Transfer -> Export to netlist”) and then open this netlistfile you created, you will see that you get alot of strange messages (and faults). Most components will be virtual, and some pins wont be connected.

This is very strange.

And why would it be a difference between using LED A and LEDA? Must this be a special word here? I thought that I could chose my own name for it.

Thanks for all the help!

Hello NI
Unfortunately, I did not find the component LM3146A or CA3146A (High Voltage Transistor Array) in the NI Multisim,So I shall be very appreciative if someone from the NI Group is able to provide me with this component in order to simulate my circuit.Thanks alot.
my best regards

I have created a model file for your component. I used Ideal Transistors to make it so I don't know if this will suit your purpose. I will post the model and if you need to you can adjust the transistor specification inside the model to what you need. I have tested it and it does seem to work. Here's the model:

I made an error in my design of this component. I had transistor Q2 flipped in the wrong direction. I have corrected this error and will post the new component model file below.
