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?
With LTC6560 and ADG658, there is a problem with ADG658.For some reason, I ca n’t upload files, only screenshots
This is a simulation diagram. The model used is cir downloaded from the official website, and then generated asy and lib
To upload your simulation file and see if somebody can help you, I suggest that you create a zip file. You can upload a zip file here on EZ no problem. *.asc files cannot be directly uploaded on Engineer Zone but zip files can.
Within the zip file, please include the *.cir (model file), *.asy (LTspice assembly file) for ADG658. Also, include the *.asc (simulation file) which you're having issues with.
Thanks for your suggestion, I cannot upload because the file is encrypted, I will re-create a project upload later
