Does this mean a feature like 'virtual components' with prerouted wires and vias will be possible? (Modularize a project by creating MCM components as KICAD modules) I don't know if this will be easy to map subsheets to such a 'component'. Maybe there is a mechanism to logically group together some chips and other parts to be in a 'MCM' module. But when thinking about a simple 7400 chip, it has sub circuits that could be placed separately, but it is still one component. Are there posts and ideas about 'subsheet as a component'? > A board like this cannot be done without bridging to freerouter > however.
