How to design a circuit program

The first step, you need to design the program to achieve the function or to achieve the goal;

The second step, you are clear about the design of the program's process requirements and constraints;

These two steps must be repeated to confirm that more inquiries, more discussion, the more detailed and comprehensive the better, do not have any details of the omission. Then these contents are compiled into a design task book, as the design basis for the record (preferably signed by the relevant parties to confirm), easy to query. Sometimes the design task book do not have to write their own, customers or leaders will write a good to you, you can do it;

The third step, drawing program block diagram, the method will not go into detail. The block diagram should be drawn in detail, rather than draw more may not be useful, do not leave out what may be useful;

The fourth step, to determine the program, listing two options that can be selected, first choose one to carry out;

The fifth step, to select the core components and the main components, and sometimes you must do some simple calculations, the components and calculated values are listed in the table, especially the interface parameters are listed to determine that each interface between the components is not a problem;

Step six, if the program has a requirement for cost, then repeat step five for another program. Then do a price comparison. Of course, the main consideration is cost-effective;

Seventh step, report the program for approval;

Eighth step, drawing circuit schematic diagrams, component parts layout, wiring diagrams, enclosure or cabinet diagrams, list of materials.

I hope it helps you!
