Use the options in the Class Generation tab to configure the automatically generated classes you require, and if you want to create user-defined classes during design synchronization. The generation of these are configured in the Class Generation tab of the Options for Project dialog (the synchronization is controlled by options in the Comparator tab). User-defined classes - derived from design directives placed by the designer.Automatic classes - derived from the buses/harness, components, or sheet contents and.When transferring the design from the schematic to PCB, Altium NEXUS provides support for generation of component and net classes. There are two types of classes that can be generated from the schematic and synchronized to the PCB: Generation and Synchronization of Classes from the Schematic An object can belong to more than one class.Īlso, Structure Classes can be created. A Structure Class is a special type of class that can hold, as its members, any type of class. Parent page: Managing Design Changes between the Schematic & PCBĬlasses are provided to enable various commands to operate on subsets of object types, for example, a group of components or a group of nets.
