Even though it can be painful to spread a large design file through a lot of sheets in a flat schematic circuit design, many users will view this as the lesser of two evils in order to avoid working with hierarchy. I know this because I used to be one of those design engineers.ĭepending on the printed circuit design CAD system that you are using, there may be a lot of work ahead of you to create a hierarchical design.

The problem is that a lot of designers will avoid using hierarchy at any cost because it can be difficult to work with. By including a top hierarchical sheet in your schematic, you can represent the circuit creation design with a logical hierarchical block that represents the actual lower sheets of circuitry in the schematic. Using a hierarchical schematic circuit design flow to organize a larger schematic makes it even better. Placing and connecting the netlist together so that their logic flows naturally can give you a feeling of great accomplishment. If you're manually annotating your schematics, then I'm not sure how effective the 'Complete Existing Packages' option is.There is a lot of joy in creating a new world schematic circuit design. If the parts are already linked to separate PCB components then even resetting them and re-annotating them might not get what you want, which is why I suggested it might be easier to delete and re-add one of them. If you had a bunch of the same part all with reset designators then it might pick two other instances to make a complete package, but should still try to make complete packages across schematic sheets. If you reset just those two designators, and then annotate the schematic with 'Complete Existing Packages' set to 'Whole Project' it should see that those parts can be fit into one physical package and annotate them that way (as long as one is A and one is B). Yes, if the designators are already set then Altium won't annotate them and won't assign them to the same package.
