By default LTspice uses a set of colors suited only for displaying on a computer screen, but with a couple of problems:
Fortunately, the colors can be changed easily. From the “Tools” menu pick “Color preferences”.
From the “Color palette editor” pick the “WaveForm” tab.
For every “Selected Item” from the table below we set the colors:
Now the “Preview” area should look like this:
Using the same steps as above, go to the “Color Palette Editor”.
From here configure the following items:
From the menus, we choose:
Edit ⇨ Draw ⇨ Rectangle, do draw a rectangle;
Edit ⇨ Text, do add a text comment.
With these, we split larger circuits into blocks, and label these blocks. The text comments are ignored by the simulation engine, being useful only for the end-users.
We can tie together two points on the schematic without drawing a wire between them. If two points on the schematics are labeled with the same “net” name, the simulation backend considers them as being the same. Another useful detail is that on the chart resulting from the simulation, the traces are labeled with their net name.
We can observe the following details:
