Example here: [https://easyeda.com/pmc/question1](https://easyeda.com/pmc/question1) Sim works with Model and SUBCKT name "myAD823A". When op amp Model name is "AD823A", sim fails with "Fatal Error: Ada4700: Missing node(s)." This happens when the Model property of the op amp is "AD823A" regardless of SUBCKT name in model text or if model text is "comment" instead of "spice". I assume there is a broken "AD823A" model somewhere, but I can't find it by searching system or user contributions. No "Ada4700" appears in the netlist. * Is this correct behavior? * Is there a way to find what the AD823A model name resolves to? * Is there a way to force a component Model name to resolve to the model in the schematic? Thanks for reading.
