I was working on a circuit today and things seemed just fine until I clicked "run" and got this error message : "Couldn't open library file "MyDigital.lib".

Any idea why am getting this error?

I attached the circuit below.

Note: I couldn't have the TLP350 component in the circuit unless I have it in the same folder of the circuit, so I attached them both here.


Thanks

 

Hi

Did you autogenerate the symbol from within LTSpice? I ask because the file MyDigital.Lib is embedded in the symbol file and is specified as the SpiceModel property value of the symbol.

If this is the model from Toshiba, it is encrypted for PSpice so it is unusable in LTspice.

To be honest, I don't know!!! I just got this model as is, no extra info............ actually I was given the following text file as well (check attached file too):

Hi

I fixed the symbol and model file.
I didn't verify the model behavior.
Use the attached files.

Thank you so much eetech for your efforts to help me out.... i will try it and let you know once i get off work later this evening... thanks again

Amazing! I just run it and it is fabulous! Really I can't thank you enough eetech.

 

Glad it worked...

Hii eetech,

actually i have also the same problem. But i donot know exactly what i have to do in order to solve this issue
this is my error *Could not open library file AUIR08152S*

I get the Spice model from here:

https://www.infineon.com/cms/en/product/power/gate-driver-ics/auir08152s/#!simulation

Now what i do only is, autogenerate the symbol from this spice model and take this symbol into my circuit only.
- Then I open the *Component attribute Editor* nd place the name of the IC in the Value.
- Then i go into * Edit Text on the Schematic* and choose Spice.lib directive & place the link below .lib AUIR08152S.txt


When i click on the Run. The Fatal error comes *Could not open library file AUIR08152S*

I make one folder in which i place all these files. This Folder location is at my desktop and my LTSPICE is install in universal location where windows install and in Programmer
Simulation mit NPN.asc
AUIR08152S.txt
Also the Spi file of this model which i have mention through the link.

Kindly tell me in brief actually what mistake i m doing right now.





I m axiously waiting for your reply.

Hi

You did everything right except the model file from Infineon has an error.
Attached is "fixed" version. Try this one

Thanks it works. but i cannot able to see the waveforms. When i click on the Run button. It shows a Text file showing me the current and voltage. I need to check at the output any voltage. I cannot access to the waveform task bar. Why is it so ??

Thanks atleast you make it in Working Condition

Thanks

Have a nice weekend.

Are you doing a .tran analysis? (Sounds like you're doing a .dc one).

 

hi,
I tried a .tran on that asc file post#9, it would not converge, left it for ages.

DC op completes in .340 seconds

I just tried a .tran on the same schematic.
It completed in .634 seconds.

I didn't check the circuit, just corrected the .model file

hi eetech,
I will rerun it see if I can find the problem at my end, just changed over to Win 10 and LTS XVII.

Update:
This is what I get for the full circuit, post#9, tran set for 5m

 

Thanks alot to all yes it works now.
