The design and application of Protel 2004 based tutorial and guidance on the machine Edited by Liu Wentao The fifth chapter hierarchical circuit design Teaching tips: circuit diagram for larger and more complex, the best way to module design, it needs to manage in a hierarchical way circuit diagram. Schematic drawing of the hierarchical functional modules from largely the circuit decomposition clearer, and is convenient for the staff to check and modify the electrical connection circuit. This chapter will introduce the design method of hierarchical circuit diagram. Teaching goal: through the study of this chapter, the basic knowledge and operation can help users skilled and consolidate the Protel 2004 level circuit, and a circuit design into a larger module type, with circuit level. The concept of 5.1 level hierarchical circuit diagram The hierarchical circuit according to the function of dividing circuit, the circuit diagram represents a function. So in the circuit diagram, you will see many circuit diagram, it is easy to understand the overall structure of this circuit; if you want to further understand the details, see circuit a circuit diagram, can also enter the circuit diagram, look at the local. Of course, if the circuit block diagram is very complex, you can also continue to block instead of a part of the function, so that a layer of it, this is a hierarchical circuit diagram. The concept of 5.1 level hierarchical circuit diagram For a two layer structure, there are 11 examples of c
