Hi I'm just starting out with LTspice and wanted to do a simple experiment with a 555 timer.
I'm using a model file from http://www.irtc-hq.com/IRTCLIB1.txt (the "555" model). I have a .include spice directive for this file on my hard drive. I'm using the DIP8 assembly in LTspice to model the 555 and have all connections made. I'm learning so I know some of this may not be right
When I go to simulate, I get this error: "undefined sub circuit: inv" - what did I do wrong to miss? I did edit the DIP8 assembly to have the "X" prefix and in the value I put "555".
Here's the contents of my ".asc" file (having upload issues). Would appreciate any help, I'm kinda stuck.
