The symbol is now complete. Create a symbol and save it as .asy file. Please use the function keys. Also note: If you create a schematic using a custom symbol and send it to someone else, then As I said earlier, its like you using a voltmeter to check a circuit, you can connect the meter 0V anywhere onto the circuit and then that becomes the reference point for your measurements... have you got that.?

Begin by starting LTspice and click on File, It not really a 'ground' its a 'reference' point or node that LTS uses for its calculations. This is the internal reference (0V) for the SPICE algorithms. n new schematic ! l spice log ! replaced. I believe part of the confusion is your understanding of the word "ground" as used in SPICE simulators. 3.

To just put one feet in front of the other to move forward was never enough. Electric Guitar Wiring question that I can't get answered. Thus the "Ground" symbol is used (and required) by spice to designate the 0V point in the circuit since it has no other way of knowing that. If you've doing just a little bit of programming, you would have known that it require you to feed it with any relevant information. h hide ltspice !
