Once the schematic has been made, it is converted into a layout that can be fabricated onto a printed circuit board (PCB). [[Schematic-driven layout]] starts with the process of [[schematic capture]]. The result is what is known as a {{visible anchor|rat's nest|Rat's nest}}. The rat's nest is a jumble of wires (lines) criss-crossing each other to their destination nodes. These wires are routed either manually or automatically by the use of electronics design automation (EDA) tools. The EDA tools arrange and rearrange the placement of components and find paths for tracks to connect various nodes. This results in the final [[Integrated circuit layout|layout]] artwork for the [[integrated circuit]] or [[printed circuit board]].<ref>

A generalized design flow may be as follows:
:Schematic → schematic capture → [[netlist]] → rat's nest → [[routing (electronic design automation)|routing]] → artwork → PCB development and etching → component mounting → testing
