I don't know what you mean by *overwhelmed* or that the other programs
are simpler. I disagree. As a user, I find thses other programs much
more difficult to use. The point is that you don't have to do anything
to get the data plotted and read, in SS.
1 Draw schematic, and place test points where you want to view signals.
2 Setup and enable, for example AC and TRAN runs
3 Press the blue "R" button.
4 Graphs for TRANS and AC will automatically open with the signals
5 Move test points to othe nodes and the graphs will be auto updated.
6 Move the mouse to the waveform trace, it will lock on and give a
direct read out of the data.
In other simulators, step 6 usually requires piddling about with cursors
and holding down the mouse button for as long as you are scanning data.
Thisis a real pain.

I agree that I have not done much checking in this manner, however there
is a downside to this. For experienced users you can end upon with all
these annoying warnings that he knows are not relevant at the time.
I don't think the issue here is setting up the sim correctly, its
knowing that a simulation need to be set up. That is if you want to see
a waveform against time, you need to know that you need to use a time
domain specked generator, and do a transient run.
I did check my help file on this, and for the most part it is explained
what each run is, although I am adding some more. The issue here is that
often users cant be bothered to read the help.

I am always open to input, and I do add suggestions in. It just depends
on the effort involved and relevance.
SuperSpice, a very affordable Mixed-Mode
Windows Simulator with Schematic Capture,
Waveform Display, FFT's and Filter Design.
