Titles representing wires, signal paths, cables, etc. Usually straight, that is, horizontal and vertical, to minimize crossing and bending.

1. Horizontal arrangement: arrange the lines of equipment and components so that their cables are usually arranged.

2. Vertical arrangement: Equipment or components are arranged vertically.

3. Cross arrangement: connect the corresponding parts into a symmetrical layout.

Layout of a circuit or component

Functional layout method: simply put, the arrangement of component symbols only considers the functional relationship it represents, without considering the layout method of actual position. In this layout, objects are divided into several functional groups, and the causal relationship is arranged from left to right or from top to bottom; The functional groups should be set together as far as possible and arranged neatly. Most electronic maps are functions. Observe the layout principle:

The layout order should be left to right or top to bottom. If the information flow or energy flow starts from right to left or from top, and the flow direction is not obvious, a hollow arrow should be drawn on the connecting line. The start arrow should not be adjacent to other symbols.
