I've not used modules but I think this will work... * Try it with just 2 channels first or even just create a simple dummy project with a simple module and some interconnecting resistors to try it out. Create the schematic for one channel; OR: If you have already created a Schematic Module for the channel, place one instance of that module into a Schematic sheet; Save it as a Schematic. Convert that to a PCB. Save the Schematic as a Schematic Module. Lay out the PCB. Save that PCB as a PCB Module. Add the rest of the circuitry needed to complete the schematic **except** for the remaining channels. Save this schematic. Convert it to a PCB. Place the PCB modules for the remaining channels to the PCB. Don't forget to enlarge the PCB outline to accommodate the extra channels. Save the PCB. Add the schematic modules for the remaining channels to the schematic. Do not change any of the component prefixes. Connect up the remaining channels. Save the schematic. Click on **Update the PCB...** in the Schematic Editor or **Import Changes...** In the PCB Editor. Route the connecting tracks in the he PCB Editor. Save the PCB.

Hi Andy, thanks! your solution works great! the only issue i got left to handle is the annotation of multi opamps component when duplicating a module. Ahiad

@Ahiad, Thanks for letting me know. :)

Hello @Ahiad and @Andyfierman, I am in the same case with five preamp channels, I want to know if schematic and PCB module in sheet are like "instance" or "pointer" to the module ? In other words, if I put 5 modules on my schematic and PCB sheet, and after, I realize i made a mistake in the module, can I just correct the module and update schematic and PCB sheet ? Or do I need to replace my 5 modules manually on both sheets ? Thanks in advance

@rom1nux, EasyEDA does not support hierarchical schematics so each module in a schematic or PCB is simply an instance. Unfortunately this means you will have to correct or replace each instance of the modules in the schematic. Then do update PCB and move and/or reroute the affected tracks and packages in the PCB.

@andyfierman, Many thanks for your quick reply. Have nice day rom1nux

Hi guys, I have created a Python script that allows to create a kind-of-multi-channel design in EasyEDA. [https://github.com/elvisfox/easyeda_multichannel/tree/master](https://github.com/elvisfox/easyeda_multichannel/tree/master) There are still things to be improved, but it already works. Below there is an example. PCB is matched with the schematic as long as the sources where matched. Please check the README at github for a short how-to-use instruction.
