PCB Detail Tutorial (iii) Improvement of schematic design

In the previous section, the design steps for PCB principles are described in one example, and this section further introduces some of the techniques in the design.

Shield : place->directive (instruction)->compile mask to block block diagrams that are not used

Add rule : Place->directive->paremeterset You can add PCB design rules to your schematic diagram

Eg: Add a patemeterset, as follows:

Click Add:

Two rules added: Minimum line width 10mil and minimum over hole 15mil, respectively

Display string : place->textstring, place string: (in the text to the right of the drop-down menu can select some special strings, such as time, date, etc.)

Display text box : place->textframe

placing notes : Place->note

To Modify component encapsulation : Dual-machine components, click Edit

Click Browse to select the package type.

Global Modification (modify all similar components): Select Component, right-click->findsimilarobject/eidt->findsimlar

Select (capacitance, package for rb7.6-15), click OK, irrelevant components will be blocked off, at this time select the need to modify all components, (mouse ring/edit->select->all), and then modify the parameters, 650) this.width=650; "src = "Http://s3.51cto.com/wyfs02/M01/59/D3/wKiom1TpXSPSJhIoAAOvt_G9pXE844.jpg" title= "1.png" alt= " Wkiom1tpxspsjhioaaovt_g9pxe844.jpg "/>

To modify the parameters here, click Enter, you can modify the component parameters, and then click Clear in the lower right corner to exit the current mode

Global modification Encapsulation (only package modification): tools->footprintmanager,650) this.width=650; "Src=" http://s3.51cto.com/wyfs02/M00/59/D0/ Wkiol1tpyhegnyivaajbhjf03as615.jpg "title=" 1.png "alt=" Wkiol1tpyhegnyivaajbhjf03as615.jpg "/>

Select the component you want to modify, display the package form of the selected component to the right, then select each form, click Edit, modify the package type, click Validata (Verify that the modified package is available), and then click Receive changes in the lower right corner.                                                                        Upon completion, all selection component packages are modified. 650) this.width=650; "src=" http://s3.51cto.com/wyfs02/M00/59/D3/wKiom1TpYDbQ5XJVAAE87OWvB6E965.jpg "title=" 2.png " alt= "Wkiom1tpydbq5xjvaae87owvb6e965.jpg"/>

generate library from schematic : design->makeschematiclibrary (extract all components from the schematic diagram)

Snippets use: in drawing schematic, may often use some common circuit, at this time you can draw the circuit well, then it is selected to click the right button->snippets, the future use of the circuit, you can click in the lower corner system-> Snippets directly selects the circuit.

distance measurement : reports->measuredistance can measure distances of two points
