Hello, I am a newbie here, I have been struggling with the following error. Any insight will be highly appreciated. I have been constantly getting the following error that unknown sbckt is present. I tried looking up these errors and it is apparent that perhaps, I dont have the required models or files present. However I looked up the directory and found those models. What could possibly be causing the error? Kindly find attached the screenshots of the SPICEDECK, the .lib file and the error message.
