I get the error message, maybe I'm forgetting something, but lost my way trying to solve this error last couple of hours.
Did the following: 1.

Downloaded a symbol with 9 ports and called it LM13700.asy (path: lib\sim\LM13700.asy) 3. Opened the symbol in LTSpice, right click and put Preface: X, SpiceName: LM13700, Value: LM13700) 4. Hooked up the LPF circuit from the LM13700 datasheet. |
