It’s a shame too because the circuitry flow can often be better represented in a hierarchical design, and a design with repeated circuitry can really benefit from using a multi-channel hierarchical approach. Even though it can be painful to spread a large design file through a lot of sheets in a flat schematic, 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 PCB 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 design with a logical hierarchical block that represent the actual lower sheets of circuitry in the schematic. Using a hierarchical schematic 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 save as a sheet to another project, please make all of the prefixes unique, if the Sheet A has a R1, and the Sheet B has a R1, then you will get a Prefix Conflict Error.There is a lot of joy in creating a schematic. If you want to arrangement the sheets order, you click the menu of the sheet icon: Move Forward/Move Backward.ĮasyEDA support global unique prefixes, when you place components in different sheet, the editor will auto annotate the prefix. You can click the Sheet tabs on the left-down corner to switch the Sheets, and right-click the sheet tab you can “Save as”, check “Histories record”, “Move Forward/Backward”,”Rename” and “Delete” the sheet. Multi-sheet designs(equivalent to a circuit spread over several pieces of paper), all schematics under the same project will be merged into one when be converted to PCB connecting in Netlabel, Netflag, Netport. All nets in EasyEDA are global so if you create a netlabel DATA0 in sheet A and then create a netlabel DATA0 in sheet B, when sheet A and sheet B are in the same project, they will be connected. You can put several schematics in one project with connections between made by NetLabels/netPorts. EasyEDA does not support true hierarchical designs but it does support multi-sheet designs.
