Alternatively, if you want to specify a custom name for all or a particular component, uncheck the Apply box under Naming Scheme column to disable the Naming Scheme for selected components and edit the PCB Component Instance column.
Use the Reset All button in the Board Level Annotate dialog to reset all of the designators back to the default names for compiled components. After components have been reset, the Prefix column will display a component icon with a question mark to show that the component is now undesignated. You can annotate your compiled sheets using the Tools » Annotation » Annotate Compiled Sheets command.
This function enables you to uniquely name the documents the physical representation of your design. Annotation file. The Navigator view of your project shows the compiled physical representation of your sheets. When you annotate the sheets Depth First , you annotate each branch of the hierarchical structure at a time. When you annotate the sheets Breadth First , you annotate the sheets based on their position in the hierarchy meaning the top sheet is annotated first and then all of the second level sheets are annotated next.
Choose Increasing or Decreasing to annotate your compiled sheets based on the Numbering Order chosen. You can create custom names for your compiled sheets by typing directly into the Sheet Number field. You can use any combination of alphanumeric or non-alphanumeric characters. After entering your custom names, click OK to implement your custom annotation.
If you have not annotated your compiled sheets, the Schematic Sheet numbering Tools » Number Schematic Sheets information will be used. Once you have annotated your compiled sheets, you can place the SheetNumber special string in your project to reference this information. Device Sheets are portable and can be re-used between designs. In most cases, the names of the components in Device Sheets are limited to the scope of that sheet and require Board Level Annotation in order to be incorporated into the design in which they are placed.
Board Level Annotation is relevant to Device Sheets due to the fact that different Device Sheets included in one project can contain duplicate designators resulting in compilation errors.
Default Names are required to be able to distinguish between the different instances of the physical representations of components. These default names are displayed in your documents and are used if you have not performed a Board Level Annotation to annotate your compiled physical components.
Default naming of compiled components is also applicable for multi-channel designs that reference the same sheet in a project multiple times. This is done by either placing multiple sheet symbols that reference the same sheet in the Schematic Document or by including the Repeat keyword in the designator of a sheet symbol to instantiate a sheet multiple times.
While this makes it easy to repeat circuitry, it also presents a challenge in terms of annotation. In a multi-channel design, there can only be one logical instance of each component with its own unique designator no matter how many "copies" of it exist on the PCB. Rooms are regions that assist in the placement and annotation of components in multi-channel designs. More specifically, a channel on the schematic is an instance of a repeated sheet and on the PCB each channel is represented by a room.
Once components have been assigned to a room, they move when the room is moved allowing separate channels to be easily controlled and identified. Logical designators are assigned to the components in the Schematic Editor View. Physical designators are assigned to the components when they are placed in the PCB design or when you have performed a Board Level Annotation. In multi-channel designs, the logical designators for repeated channel components may be the same, but each component must have a unique physical designator in the PCB design.
This can be accomplished by appending the Room Name to the component name as shown in the Component Naming field below. By controlling the multi-channel designator format in this dialog, you control the mapping from the single logical component in the Schematic Editor View to the multiple physical instances on the PCB.
The tab is essentially divided into two areas - Room Naming and Component Naming. The Multi-Channel tab allows for flexible default naming formats in multi-channel designs. Use the Room Naming Style drop-down to define the naming format you require for the rooms in your design. These rooms are created by default when you update the project schematics to the PCB. There are five styles available — two flat and three hierarchical.
As you select a room naming style from the list, the graphical representation is dynamically updated to reflect the naming convention that will appear in the design. The larger cross-hatch regions represent the upper-level channels or Banks and the shaded regions within represent the lower level channels. When the design is compiled, a room is created for each sheet in the design including each bank and each lower-level channel.
There are no restrictions on the character used for the level separator, however, a single non-alphanumeric character is easier to read. There are several designator formats available for naming components. You can choose a format or define your own using valid keywords. Define the Component Naming format by selecting from the Designator Format drop-down list. There are eight predefined formats — five flat and three that can be used in a hierarchical context:.
The Flat Designator Formats name each component designator in a linear progression, starting from the first channel, avoiding the duplication of designators. If the Room Naming Style chosen is one of the two possible flat styles, then the style for the component designator will also be flat. However, if a hierarchical style has been chosen for the Room Naming Style , the component designator will also be hierarchical since the path information will be included in the format.
You can define your own component designator format by typing directly into the Designator Format field using valid keywords. Select from any combination of the following keywords to construct the format string.
Name of the associated room as determined by the style chosen in the Room Naming Style field. Your design is constructed in the Editor tab. Compiled Documents physical representations of your design are visible and can be accessed by clicking on the Compiled Document tab located along the bottom of the Schematic Document in the design window. Examples of workspace tabs. You can specify display preferences for the physical names in compiled documents on the Schematic - Compiler page of the Preferences dialog.
You also can use the associated drop-down to select how the objects are displayed. Choices include: Never display superscript expanded names are never displayed , Always display superscript expanded names are always displayed , or Display superscript if necessary expanded names are only displayed if they are different from the source. Use the Design » Update PCB Document command to initiate a transfer process that will automatically create a component class for each schematic sheet in the design, a room for each component class, and group the components in each class in their room ready for placement.
A key ingredient of good board design is component layout. In a large design, a component's position on the board may have no relationship to its designator. For example, R1 may end up on the opposite side of the board to R2. To make it easier to locate a component on the board, you can reassign the designators re-annotate the board positionally.
The Positional Re-Annotate dialog includes a graphical representation of each method. Each component is identified by its bounding rectangle excluding strings. The components are sorted into a list and the list is renumbered in that order to create the new component designations. To compare two components in the X-direction, the left-side of the bounding rectangle is used. To compare two components in the Y-direction, the edge used depends upon the renumber direction: ascending-Y, use the bottom edge; descending-Y, use the top edge.
The Comparison Threshold option can be used as a buffer value when comparing two edges to determine if they are equal. For example, if two left-edges are within This allows for slightly misaligned components to be re-numbered in a logical order as shown in the image below. Here R27 is lower than the other resistors to keep it correctly annotated with the adjacent resistors the Comparison Threshold was set to 10mils.
A series of resistors that have been positionally re-annotated. Note that R27 has remained in the annotation sequence even though it is lower than the other resistors. The Annotate Scope options also give control of the annotation process for boards with components mounted on both sides.
For the Bottom Side of the board, components are re-annotated as if you are looking at the board flipped over. So, for the X-direction comparison on the back-side, the software actually uses the right edge of the bounding rectangle remembering that viewed from the back side, this edge would look like the left side. Note that a rotated component is identified by the smallest bounding rectangle that encompasses the original bounding rectangle in its new rotated orientation as shown in the images below.
The image on the left shows the bounding rectangle for R2; the image on the right shows the new bounding rectangle when R2 is rotated. The file lists initial and re-annotated designator values. WAS file also can be used to load the changes into the schematic if the PCB and schematic files are in different locations. To prevent a component from having its designator re-assigned, enable the Protect Locked Designators checkbox in the Positional Re-Annotate dialog and ensure that the Strings locked icon is enabled in the associated Properties panel as shown below.
You can either choose naming options that result in a short name or display the original, logical component designation instead. This would necessitate some other notation being added to the board to indicate the separate channels, such as a box being drawn around each channel on the component overlay.
If you choose to display the logical designators for components in a multi-channel design, these will be displayed on the PCB and in any output generated such as prints and Gerbers. The unique physical designators, however, are always used when generating a Bill of Materials. Design Synchronization compares the components and connectivity of the schematic directly to the PCB, producing a list of differences.
An ECO file describes the differences between the current design and the desired design and can be executed, updating the target and bringing the design into synchronization. The terms Forward Synchronization and Back Synchronization are specific ways of describing the direction that annotation and design changes are transferred during the synchronization of data. Visualizing a design flow that starts with, and is driven by, the schematic, Forward Synchronization is the process of updating changes made in the Schematic Editor forward to the PCB.
Choose from one of the following methods to synchronize your Schematic design forward to your PCB design:. Back Synchronization is done when you have annotated or changed your PCB design and you want to update the schematic design. Choose from one of the following methods to synchronize your PCB design back to your schematic design:. Uncheck this option to push changes to the source schematic document only Editor view. The preferred method for synchronizing your design is Direct Design Synchronization.
If you have re-annotated your design, the schematic component designators or the compiled component designators will no longer match the PCB component designators, so synchronization is required to successfully close off the design. Rather than relying on the designator itself as the key field that relates a schematic symbol to its equivalent PCB footprint, Altium Designer can maintain design synchronization through the Unique IDentifier UID system.
The UID is a system-generated value that uniquely identifies the source component and matches each schematic component to the corresponding PCB component. When a component is placed on a schematic sheet, it is automatically assigned a UID. The first time component information is transferred from source schematic documents to a blank PCB, the UID information from each schematic component is assigned to the corresponding PCB component.
Refactoring allows you to convert Device Sheets to Schematic Sheets and vice versa while maintaining the Unique ID of the sheet and its components. In addition, you can refactor or move subcircuits to other schematic sheets in the current project, maintaining the Unique ID of the subcircuit.
The Refactor command is located on the Edit menu. An ECO lists all modifications required to implement changes to one or more design documents in order to satisfy the synchronization action requested. ECOs are used to affect design updates in a variety of situations, such as:. Use the dialog at any stage during the design to view the linking between the components to verify that components between documents are correctly matched, as well as to assign matching UIDs to components that are currently unmatched.
If you are planning on re-annotating either the schematic or the PCB, it is essential that you make sure that the UIDs are matching first, since once you change all the designators on the schematic or PCB, the UID is then the only piece of information that can be used to link the schematic component to its PCB equivalent. Annotating the Components in a Design in Altium Designer.
Using Altium Documentation. When Altium Designer processes components for annotation, it applies a bounding rectangle that encompasses the complete component and all visible parameters. If the order of processing does not seem to be correct, check the position of component parameters to ensure they are not adversely impacting the result.
When selecting the Completing Existing Packages option, consideration should be given to how power pins have been specified on active components. If the first part in a multi-part component is packed into an alternate package and has its sub-part updated, it can lead to unconnected or floating power connections. Multi-part components can use either an alpha or numeric part identifier suffix - i. Control over the style of suffix is specified on the Schematic - General page of the Preferences dialog.
Note that Preferences are global and apply to all currently open schematic sheets. The Reset All drop-down button can also be used to Reset Duplicates. Parts to be excluded or included in Board Level Annotation need to be selected before you open the Board Level Annotate dialog.
If the component is undesignated, it will have a component icon with a question mark. After you perform the first Board Level Annotation, the icon changes to denoting that the component has a designator. If you reset the designators, the icon will revert to. Note that Back Annotation is a legacy tool and it is best practice to use Design » Update to push annotation changes from the PCB back to the schematic.
The superscript options are applicable to both the Editor tab and your Compiled Document tabs. In the Editor tab, the compiled names are in superscript and in the Compiled Document tabs, the logical name the name in the Editor tab is displayed in superscript. This is a legacy tool. The preferred method of design synchronization is the Design » Update Schematics command. Back Annotate Schematics synchronizes annotation changes made in the PCB editor with the schematic design.

The Board Shape is created from one or more Board Regions. For designers working on a single-region board design, the following commands can be used to define the Board Shape:. The difference between the Define Board Shape from Selected Objects command and the Create Board Region from Selected Objects command is that the first command replaces all existing Board Regions with the new region that is created when the command is run, whereas the second command creates an additional Board Region, without removing any existing Board Region s.
The video demonstrates creating the Board Shape from selected objects and then placing Split Lines to create the three regions needed. The video first demonstrates creating the Board Shape from selected objects and then slicing the shape to create the three regions needed. Then it shows an alternate approach, where the three Board Regions are defined from selected objects. Note that these demonstrations are using Rigid-Flex 2. The next step is to import the board's shape as a.
DXF or. DWG file. Note that the shape to be imported must be a closed shape and internal cutouts are not automatically created but can be defined later from imported objects. The software will attempt to find the shape based on the centerline of the selected objects.
It will offer to use a tracing algorithm instead. Only choose this option if your design can accept the impact of this difference.
This feature redefines the board shape based on a surface face of an imported 3D model. It can be used to quickly create a complex board shape and helps integration between electronic and mechanical design areas. You will also be prompted to update the shape, which helps if the shape is still under development and updates are expected.
Only surfaces aligned with the X-Y plane can be used to create the board shape. If you select a model surface that requires alignment in the X-Y plane, you will be asked in a Confirmation dialog to align the surface before you can continue. This dialog also allows you to place the model using the selected face in relation to either the top or bottom surface of the board.
This means that the vertical position of the model can also be set at the same time. After the board shape has been redefined, you will be given the option to hide the 3D body. Use this command when the Board Shape exists but there are currently no objects along the boundary. Situations where this command can be useful include:. A board cutout can be placed anywhere in the Board Shape. Note that the cutout is actually a Region object configured to be a negative object.
A Board Cutout has been placed on the Board Shape. If the board cutout is an unusual shape, such as a circle, it can be easier to create an outline of the cutout shape using tracks and arcs for example, Place » Arc » Full Circle , select the shape, and then convert it to a Board Cutout Tools » Convert » Create Board Cutout from Selected Primitives.
Polygons that overlay a solid region board cutout will pour as close to the edge of the cutout as allowed by the applicable Clearance design rule. A specific Clearance design rule can be created if required, which could, for example, be scoped to apply between IsBoardCutoutRegion and InPolygon.
A common approach used to cut the finished board from the fabrication panel is to mill or route the board out of the panel. Board cutouts can also be routed out.
