Schematic design is the foundation of circuit design, and only after designing the schematic can the design of printed circuit boards and circuit simulation be carried out.

The quality of circuit schematic design will directly affect subsequent work. In general, when designing a circuit schematic, the first step is to set the parameters of the drawing in the schematic editor. Then, the overall planning of the circuit diagram should be carried out, and components should be placed on the drawing for layout and wiring. After the preliminary drawing of the circuit schematic is completed, annotations should be added and checked and modified as needed. Finally, the designed drawing should be printed out.
