Original Question: ADA4941-1 .cir by sss
Hi all,
Our customer tryed to simulate the ADA4941-1 with ADIsimPE.They downloaded the ADA4941 SPICE Macro Model from web linked page .
But the error occured with following error massage.
"*** ERROR *** The circuit is too large to simulate with this version.Too many analog nodes
Test circuit is the ada4941-1 parts only from "Figure 57. ADA4941-1 Driving the AD7687 ADC" @ datasheet.What is happens ?
Best regards,sss

Hi,
The error is normal for too large SPICE models that exceeds circuit nodes limitation of the simulator. What we have to do is to have the .cir file encrypted. What parameters are trying to simulate here? I could have it simulated while waiting for model encryption.
Regards.

See attached file.
Hi Victor,
Did you remove the first ADA4941 model you imported to ADIsimPe? I believe the simulator is still seeing the previous one, which non-encrypted.
Anyway, try this.

Hi Jinol,
I have downloaded your attached encrypted .cir file for ADA4941. But it still popped up "
*** ERROR *** The circuit is too large to simulate with this version.
Too many analog nodes
"
Could you help? Thanks.
Hi
I just delete that part in schematic and add this part from recent added model. How to delete old part library?
Thanks
Victor
Could you provide details on what parameters are you trying you simulate? Also, a picture of the schematic would help.
Attached is the schematic. Can you run on your side with ADIsimPE? Thank you.
Regards
It is working well following your method. Thank you for help.
