OrCAD Tutorial: How to Replace and Update Components
Sometimes it is necessary to batch replace one element in the schematic, or to add attribute values ​​to the same type of element. This requires the use of replace cache and update cache commands.
Batch replace replace cache
Open the cache, select the components to be replaced, as shown
Right click, replace cache
Popup replacement dialog
Browse selects the component library and the new part name field selects the new component. This component is used to replace the original component.
AcTIon choose whether to retain the original attributes, if you select, then the original element number and other information is retained, if you choose replace schemaTIc properTIes, the original attributes are all lost, use the default properties in the component library to replace. OK, perform the replacement.
Bulk update cache
Open cache
2. Select the component to update
Right-click update cache
The two commands are similar, but there are differences.
1. The replace cache can change the connection of the component library and select different libraries. You can make different components, or in different libraries. The update cache cannot change the connection between the components in the schematic and the component library, but only brings in the new user properTIes attribute.
2. If you add component footprint information in the component library and want to bring the cache operation to the schematic, you can only use the replace cache command.
Terminals can be divided into UK terminal, European terminal series, plug-in terminal series, transformer terminal, building wiring terminal, fence type terminal series, spring type terminal series, rail type terminal series, through the wall Type terminal series.It is able to achieve safe, reliable and effective connection, especially in the environment of high current and high voltage.
