Rearrangement of tag number of cadence OrCAD components and sequence number of schematic page

One . Why do I need to rearrange the tag numbers of components

In the process of drawing schematic diagram , There are many operations of adding, deleting and modifying , This makes the tag number of components usually confused . After drawing , Usually you need to rearrange the tag number , In this way, the component tag numbers of the same function block are adjacent , This makes the painting PCB It is convenient to determine the approximate position of a component .

stay PCB After drawing , It can also be in PCB The upper rearrangement number is marked back to the schematic diagram , For the operation of this part, please refer to my other blog ：

Two . Why do I need to rearrange the serial number of the schematic page

stay Orcad in , The order of schematic page display is determined by the order of numbers and letters , amount to Windows Sort by file name in the system .

however , When exporting schematic diagram PDF In operation , A lot of times PDF The order of schematic pages in is not Orcad The order shown in , As shown in the figure below ：

actually , export PDF The default order of pages is based on Orcad Time sequence of creating a new schematic page in , The early ones are in front .

About Orcad How to export a bookmarked schematic page , Please refer to my other blog ：

Cadence Schematic export intelligence PDF（ With drawing sheet 、 Tag number and network name bookmark and text searchable ）_ Xu Dakang's blog -CSDN Blog _cadence export pdf Schematic diagram

If you want to export PDF Order of pages and Orcad The order shown in is the same , You need to rearrange the serial number of the schematic page .

3、 ... and . Component tag rearrangement

Tools → Annotate, Or click directly Annotate The shortcut icon for , It is shown as follows ：

The relevant options are explained below ：

• Incremental reference update： Incremental tag update , Do not change devices that already have tag numbers , Only the components without tag number are numbered , And the tags with more existing tags are increased , It's not from 1 Start
• Unconditional reference update： Unconditional tag update , from 1 Start numbering all components
• Reset part references to “?”： Reset the tag number to ？
• Add Intersheet References： Add cross tag , Never used
• Delete Intersheet References： Delete cross tag , Never used
• Update Occurences（Preferred）： Update Events （ recommend ）, Update each component , Each component has a unique Occurences. Tag rearrangement is to rearrange each component , So choose this
• Update Instances： Update instance , The same device shares one instance , Like two 10k/0603 The capacitors of share one example , This item is not selected for tag rearrangement
• Reset reference numbers to begin at 1 in each page ： The tag number of each page is heavy 1 Start arranging
• Annotate as per PM page ordering： Rearrange the serial number of the schematic page
• Do not change the page number： Do not change the schematic page number
• Annotate as per PM page ordering： Rearrange tag numbers according to the sequence of schematic pages

The following options have not been used , Never mind . It is applicable to the steps of tag number rearrangement in the new design （ Directly select the unconditional update tag number ）：

Four . Schematic page sequence number rearrangement

4.1 Check the serial number of the schematic page, that is Page Number

Select a schematic page Right click → Schematic Page Properties

4.2 Place a title bar on each schematic page, that is Title Block

Place → Title Block…

4.3 Choose any title bar , Such as TitleBlock0, Click on OK place

4.3 After the title bar is placed on all schematic pages , Click on Annotate

At this point to see Page Number perhaps TitleBlock Medium Sheet You can view the serial number of the schematic page , export PDF The page order of is in the order of this serial number .

Export PDF Page will find ,PDF Order of pages and Orcad The order shown in is the same , As shown in the figure below ：
