This schematic can also be used in a flat project, where the schematic is just replicated multiple times in multiple sheets. A second, blank schematic sheet (“Channel_2.SchDoc”) can be added to the Project we want to copy the circuitry in Channel_1 to our new schematic sheet Channel_2. Ports have been placed in the above schematic to show where connections will be made within the design hierarchy or as part of a flat project. The Channel_1 schematic will be used for circuit replication If you want to maintain a flat project, you can also perform design block reuse by copying these circuit blocks across a project. This would be done by placing a Sheet Symbol in the parent-level schematic, as is normally done in hierarchical design. This sheet is named “Channel_1.SchDoc”, as shown below. In our example, Channel_1 can be reused multiple times in a different schematic, i.e., it can be used as a child schematic as part of design reuse in a schematic hierarchy. We’ll start by creating a power regulator section on the first schematic sheet for a new project.

Let’s walk through an example to see how this works. Step 1 - Schematic Design and Circuit Replication Once you've finished your schematics and are working on your layout, there is one bit of manual intervention required by the user during the process to ensure easy replication and synchronization between the PCB layout design and schematics. Whether you're using a flat design with multiple sheets or creating a design hierarchy, you’ll find that Altium Designer will automate most of the circuit replication work for you. Whatever the case, there are a number of legitimate occasions where a Project is set up as flat, but circuit replication is necessary within a single schematic and as part of a hierarchy to enable circuit replication and design reuse. Some projects might be too simple to warrant setting an entire design as hierarchical. There are many users, however, who have not worked with hierarchical designs and feel more comfortable using a flat design methodology. This makes replication of circuit blocks easy as any change to the underlying circuit only needs to be made once. Once you have an existing schematic, you can copy board blocks into new sheets, or you can place symbols that represent other schematics. No matter how you choose to do multi-channel design, the main advantage is the ease of circuit replication and design block reuse. repeating circuitry within a single design). Altium Designer offers many methods for multi-channel design (i.e.
