Miscellaneous plugins for KiCad

Reproduce schematic layout in PCB layout

Based on an original idea by @jenschr

Versions:

• SchematicPositionsToLayout.py: KiCad v7,KiCad v8.
• SchematicPositionsToLayout_V5_V6.py: KiCad v5 and v6.

The SchematicPositionsToLayout.py plugin helps with the initial organisation of parts when first creating a PCB layout from a schematic. Install the SchematicPositionsToLayout.py in your KiCad plugins folder and refresh your plugin list in Pcbnew. Then to use the plugin:

1. Create a netlist from your schematic.

2. Create a new PCB layout and import the netlist you created.

3. Select "Schematic positions -> PCB positions" from the "Tools" -> "External plugins..." menu in Pcbnew.

The result of this action will be that the component footprints in Pcbnew will be laid out in the same pattern as their corresponding components in the schematic. Hierarchical sheets are laid out one after another down the page in non-overlapping areas.

The movement of the component footprints by the plugin is a normal editing action, so can be undone if you don't like what you see.

Note that the footprint organisation produced by this script is intended only to aid with keeping track of where everything is at the very start of component placement. For example, if you have a large number of decoupling capacitors for a component, you can place them near to the component in the schematic and the plugin will move them to be near to the component in the layout too. Another example where this might be useful is for analog sections where it might be useful to mirror signal flow and component placement on the schematic in an initial view of the PCB layout.
