KiCad supports an integrated design workflow in which a schematic and corresponding PCB are designed together, as well as standalone workflows for special uses.

They also affect schematic connectivity for stacked symbol pins. Esc ~ 8 Place a junction. This connects two crossing They do not connect anything. Place a bitmap image. Delete clicked items. Grids and snapping Schematic elements such as symbols, wires, text, and graphic lines are snapped to the grid when moving, dragging

可以被输入为 2 * 2 mm ，结果是 4 mm 的值。支持基本算术运算符以及用于定义运算顺序的圆括号。 使用符号工作 放置符号 To place a symbol in your schematic, use the button or the hotkey. The Choose Symbols dialog appears and lets you select a symbol 隐藏，并启用或禁用所需的 列。默认情况下，不是所有的列都显示。 The Update Symbol from Library… button is used to update the schematic’s copy of the symbol to match the copy in the library. The Change Symbol… button is used to swap added to the schematic, KiCad embeds a copy of the library symbol in the schematic so that the schematic is independent of the system libraries. Symbols that have been added to the schematic are not automatically

之间进行双向交叉探测。 有几种不同类型的交叉探测。 Selection cross-probing allows you to select a symbol or pin in the schematic to select the corresponding footprint or pad in the PCB (if one exists) and vice-versa. By default from the schematic to the PCB by right-clicking an object and selecting Select on PCB, or from the PCB to the schematic by right-clicking an object and choosing Select → Select on Schematic. 高亮交叉探测 Footprints are automatically added to the board when the PCB is updated from the schematic. The footprint associated with each schematic symbol is added to the board if it is not already present, and each footprint

file *.net Netlist file created from the schematic, and read by the board editor. Note that the recommended workflow for transferring information from the schematic to the board does not require the use components used in the schematic and their footprints. It can be created by the Board Editor and imported by the Schematic Editor. Its purpose is to import changes from the board to the schematic, for users who and want to import these changes back to the schematic. Note that the recommended workflow for transferring information from the board to the schematic does not require the use of .cmp files. 4 制造和文档文件

Clear Net Highlight action (hotkey ) or by using the Highlight net tool on an empty region in the schematic. By default, also clears net highlighting, but this can be disabled if desired in Preferences ，它将 被替换为 版本：1.0 。 Text variables can also be created in Schematic Setup. Text variables are project-wide; variables created in the schematic editor are also available in the board editor, and vice versa of the Default class, which always exists. Net classes may be created and edited in either the Schematic or Board Setup dialogs. 15 网络类部分的上部有一个表格，显示了设计中的网络类和适用于每个网络类的设计规则。 每个类别都有铜的间隙、 布线宽度、过孔尺寸和差分对尺寸的值。

approximately 4 meters by 4 meters. KiCad 目前支持每个工程/原理图一个电路板文件。 从原理图开始 Creating a board from a schematic is the recommended workflow for KiCad. When you create a new project, KiCad will generate an empty you have created a schematic, simply open the board file. You can do this either from the KiCad project manager, or by clicking the "Open PCB in board editor" button in the schematic editor. To import import the schematic design information into the board editor, including footprints and net connections, use the Tools → Update Schematic from PCB… action ( ). You can also use the icon in the top toolbar

toolbar at the left side of the schematic editor screen contains basic display settings. The toolbar at the right side of the screen contains tools for editing the schematic. KiCad 中的大多数工具要么有默认的快捷键，要么可 页面设置。给原理图一个标题和日 期，如果需要的话，改变原理图大小。 10 将符号添加到原理图中 Start making the circuit by adding some symbols to the schematic. Open the Choose Symbol dialog by clicking the Add Symbols button on the right side of the window Labels button in the right toolbar ( ), type a label name ( led ), and place the label into the schematic so that the square attachment point overlaps with the wire. Rotate and align the label as necessary
