How to do DC Operating Point w/ Autitrax?

Apr 27, 2005 0 Replies

I'm was looking at using PSpice and OrcadLite, doing simple


2 resistor, 1 volt source and 1 node gnd, DC Operating Point

and decided to try using Autotrax 3.12, since I bought it.


I placed the 3 parts down: battery, 2 resistors.



I clicked on the part's end point and stretched the node to the



next part's end point. Ok, this is wrong. Delete all of these lines.



Try using the 'ADD WIRE' icon, way top right, 4th icon.



Now there are not so many errors. But still not right, can't do



DC Opertaing Point.

Note: can't find init file.
