I am using dual/quad opamps/comparators using simple 3-terminal opamp symbols (OPAMP1) along with a 2-terminal power symbol (POWER1). I am trying to figure out how to use this in EasySpice.

Let's say IC1 is a LM393; IC1a and IC1b are the comparators and IC1c is the power symbol. So I have these properties:

SpiceDevice=X
SpiceSubcircuit=LM393
SpicePowerSymbol=IC1c

Is this right? So what do I enter for SpicePinOrder? Wouldn't IC1a and IC1b require different pin order entries?

Thanks,
Carl

OK, I got it after some T&E. I need

SpicePowerSymbol=POWER1
SpicePinOrder=2 1 V+ V- 3

Just need to assign unique terminal names to the power symbol, i.e., "V+" for pin 1.
