Three steps of PCB circuit design

Hardware circuit designers need to follow certain steps when designing circuits. You know, working strictly in accordance with the steps is a necessary prerequisite for designing a perfect circuit. For general PCB circuit design, the process is mainly divided into the following three steps:

1. Design circuit schematic diagram At the beginning of circuit design, the function and electrical connection diagram of the entire circuit must be determined first. Users can use all the tools provided by Protel99 to draw a satisfactory schematic diagram to provide reliable basis and guarantee for the next few working steps.

2. Generate a netlist If you want to convert the designed schematic diagram into a PCB diagram that can be made into a circuit board, you must go through the bridge of the netlist. After the schematic diagram is designed, a netlist file can be generated through the electrical connection relationship of the components given in the schematic diagram. The user can draw the circuit board based on this netlist by quoting it under the PCB design system.

3. Designing the printed circuit board Before designing the printed circuit board, it is necessary to obtain the electrical connection and packaging form from the network table, and through these packaging forms and the electrical connection characteristics of the components recorded in the network table, connect the pins of the components with signal lines Connect them, and then use manual or automatic wiring to complete the production of the PCB board.
