I remember trying what I think was the exact same "library" in LTSpice, and never got it to work. I think the "speed" parameter is an extra parameter that should be passed in the Spice line (you can add it when you right click on the component?), but there were tons of others errors after that, so I gave up (and found the model I was looking for elsewhere). If anyone manages to use this "library", don't hesistate to chime in.
