For more information on integrated libraries, refer to the Working with Custom Pad Shapes article.For background information on components and libraries, refer to the Understanding Models, Components, and Libraries article.This document details those tools - tools that enable you to always retain synchronicity between your component source and the placed instances of those components. Altium provides a variety of update tools that allow you to quickly and efficiently pass component changes to your Altium NEXUS components. Once changes are made, they need to be pushed across to the design. For parameters, changes are made in the database. The symbol and model changes are made in the source libraries. You also may have linked a placed component to an external database using a Database Link file ( *.DBLink). From a Schematic/PCB Library - the change is made to the component or footprint in the corresponding library from which the component/footprint was placed.

If the change is a graphical one (to a symbol or model), it is carried out within the referenced source library. From a Database Library - for a parameter or a symbol/model reference, the change is made to the corresponding record for the component in the linked external database.From an Integrated Library - the source libraries are extracted, the change is made, and the integrated library package is compiled to generate the revised integrated library.The nature of this source depends on how the component was placed: The logical place to make a change is at the source. More than likely, there will come a time when a change to a component is required - a new parameter added, a change to a model link, or maybe a change to a symbol or footprint at the graphical-level. You have placed components on the schematic, maybe even fully wired, compiled, and taken the design to the board layout stage.
