Dual comparator LTspice export - "invoked" power pins become separate .asy

I am testing the Eagle-LTspice integration and I am using Eagle library components to which I am linking spice models from manufacturer websites (IR, TI). I'm quite impressed with the LTC spice schematic export in Eagle, but it's not all plain sailing. I get a pin count mismatch error in LTspice, which I think is caused by the Invoked power pins being a separate .asy in LT. I'm using an LM2903 from the linear Eagle library, which I've linked to a TI spice model.

I would imagine keeping the power pins together in one .asy in LT would solve the problem.

Another curious problem is that when I assign a VALUE2 to a device in Eagle, I cannot right click and edit the spice fields inside LT. Remove the Value2 from eagle before export and you can edit the component in LT, but then LT struggles to locate the spice model.

First post! I'm trialing Eagle in view of buying it as our company PCB CAD tool.

Thanks in advance.

Hello Peter,

I hope you are doing well. Welcome to the forum!! You are very
observant, LTSpice doesn't worry about multiple gates so as far as
LTSpice is concerned it's seeing two different parts.

You're proposed solution should solve the problem.

Let me know if you continue to run into problems.

Best Regards,
Jorge Garcia
