Question: RE: Simulation using AD8336, AD736 and AD8551 spice models in Pspice by iamPhil

Hello Sakshi,

I'm looking into it. but have you tried running it in other simulation platform? ADISimPE?

Thanks,

Phil

Question: RE: Simulation using AD8336, AD736 and AD8551 spice models in Pspice by jstaley

Hello,

Thanks for contacting us.I have a couple of suggestions:

1.Since you are bring the AD736 and AD8336 models into the program, it is sometimes tricky to make models work. Be sure the model names and nomenclature inside the SPICE engine are spelled exactly as they are in the model, otherwise you will get the message you see. In fact the message is pretty generic, you'll see it every time there is a typo somewhere.

2. I see you're using PSPICE Lite. Such programs are usually node limited and your model is pretty large. Try testing the new models individually in a separate schematic to troubleshoot smaller files. After you get the models to work as basic parts, then connect everything together.

3. When analyzing the number of nodes in a circuit, remember SPICE also counts the nodes in a subcircuit, e.g. NPN or PNP transistors often contain multiple nodes.

4. When you get the models to run, be careful about transient analysis. You usually have to use pretty high resolution to get the model to converge, especially in circuits with feedback such as agc's.

5. The AD736 and AD8336 models were tested and we can share test reports. Please send email contact information as I was unable to attaché to this EZ inquiry.

Good luck!!

Hi Phil

Thanks for your revert. I have just tries simulating it on Pspice as of now. Any joy in debugging of the errors?

Thanks for trying, I hope I'm able to make it work.

Regards
Sakshi

Hi jstaley

Thank you for reverting. I can try working on your suggestions but I'm a complete newbie at circuit simulation, and Pspice. Have worked with Simulink a bit, long back though. I'm sure the models must be working, its just that a when we try including them in a different platform, at times there are compatibility issues due to syntax or typos as mentioned. Nonetheless, I'll be glad if you can share the test reports, I might find something useful on how to use these models. Here is the e-mail id: sakshi92111@gmail.com

Hi jstaley
Could you please help me out with this issue. I'm still not able to sort it out. Its kinda urgent. Thanks
Also, please share the test reports as suggested as soon as possible
