Except for power supply designers, providing power to your design is often a pain.
It throws ERC errors, makes simulation difficult and drags other issues along, when all you want to do is concentrate on the main design, be it analog, digital or mixed.
I made a little basic schematic that solves most of this. The idea is, that the power signals are already available in your schematic sheet before you even start designing.
The files (3) are here, save them somewhere convenient:
power.kicad_pro (13.5 KB)
power.kicad_sch (19.1 KB)
power1.kicad_sch (24.1 KB)
When you start a new design, open the “power.kicad_pro” file first. Using the “Save as…” under “File”, save it as your new project with the right name.
The power section can be modified to the voltages you need, just enter the sub-sheet and change/add/delete.
Be certain to use the built-in power symbols from library “power” and the “Simulation_SPICE” ones for the voltage sources.
Cheers.
