I'm trying to set up a simulation using a custom transistor model.  My schematic is here: [https://easyeda\.com/editor\#id=\|64304ef7d2394a47bb9c27d53624aeaa](https://easyeda.com/editor#id=|64304ef7d2394a47bb9c27d53624aeaa) Following the instructions I found here: [https://docs.easyeda.com/en/Simulation/Chapter14-Device-models/index.html#How-to-change-the-model-attached-to-a-symbol](https://docs.easyeda.com/en/Simulation/Chapter14-Device-models/index.html#How-to-change-the-model-attached-to-a-symbol) I added a generic NPN transistor from the library, and then changed its name attribute to match the name in my model directive.  I added a text item, pasted the model into it, and changed its type to be a spice directive.  However, when I run a simulation or export the netlist, the transistor is missing (although the model is correctly included). What do I need to do to get the transistor included?
