使用LTspice仿真多路复用器时出现unknown circuit node："u2:9"requested in behavioral source ，报错说未知电路节点，行为来源中要求的u2：9“。请问是什么情况导致的，要如何解决。
Unknown circuit node appears when using LTspice to simulate a multiplexer: "u2: 9" was requested in the behavior source, an error was reported that the unknown circuit was interrupted, and u2: 9 required in the behavior source. What is the cause and how can I resolve .
Which part do you try to simulate?
This is a simulation diagram. The model used is cir downloaded from the official website, and then generated asy and lib
ADG658 - 副本.zipHi,Hooman,I saw the previous discussion and re-downloaded the model for testing. However, it still is not possible. I updated and uploaded my file. Please help me to see it. Thank you.
Hi,Helmuts,thank you very mach.
I tried using your model and found that the problem was solved. Thank you so much. I wonder, what is the difference between your model and my model? I downloaded cir, opened it with LCspice, then created symbol. Can you tell me how you created it, thank you very much.
Please make a zip-file of your .asy and .cir file and upload this zip-file. I can then exactly explain what's the difference.
You can attach the zip-file to your message with
Insert -> Upload image/video file

Why have you changed the first line in the subcircuit ADG658.cir?Your change of this line is the reason why we get the error message about a missing node.Please change it back to the original content. See below.Your wrong line:.SUBCKT ADG658 D1 S8 S6 EN VSS GND A2 A1 A0 S4 S1 S2 S3 VDD S5 S7
The original line:.SUBCKT ADG658 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16
I wonder also why you renamed the subcircuit ADG658.cir with a blanc character, ADG658 .cir.There is no reason to change anything in the downloaded subcircuit from ADI's web page.
