Everyone raves (or did!) about Spice/LTSpice etc. For the uninitiated, it can appear like the Cockpit
of a Jumbo Jet, and 'Runs' by way of a short sampling of time, after you 'design' it, for your data.
However, I personally love "Circuit Wizard", that allows you to design virtually any circuit you like,
as in your example images. It has a massive array of components/data to use/modify, and can run
it continuously in Real-Time. While running, you can hover the mouse over any component/wire, and
see all the respective voltages & currents, etc.
The beauty of it, is that you can instruct it to create the final PCB for you too. Auto-arranging all the
components/tracks, and considering all the on-board & off-board components. This final view is photo
realistic with the board, and all components, and can be 'run' in this visual mode too!!
Here's a 'before' image while designing a schematic...

Here's an 'after' image, with auto PCB creation!...

You can 'run' and 'edit' it in real time from the 2nd mode above, also! And add any externals as shown.
And you can 'print' your PCB layout, with overlays, from numerous views...

P.S. Here's the example PCB Artwork!!...
