Template — displays the currently chosen via template. Use the drop-down to change the assigned via template. Library — displays to which library the via template is linked and includes the option to Unlink the template from said library.
Net — the net that the shielding vias are connected to. Via Type — use the drop-down to select the type of via from those available in the layer stack.
Via Types — click to open the Layer Stack to configure the required via types for the active layer stack. Hole Information. Hole Size — size of the hole in the shielding vias. Tolerance — negative and positive hole size tolerances allowed for the shielding vias. Size and Shape. Size and Shape — vias are one of three styles: Simple — the via diameter is the same on all layers Top-Middle-Bottom — the via diameter can be specified for the Top layer, Middle all internal layers , and Bottom layer.
Full Stack — the via diameter can be specified for every signal layer. Diameter — diameter of the shielding vias. Thermal Relief — check the Direct box then click to open the Connect Style dialog to specify the connection style.
Solder Mask Expansion. Rule — enable this option to allow the existing solder mask expansion rule to take effect on the shielding vias. Manual — enable this option to edit the mask expansion values below for these shielding vias. Top — enter the required mask expansion for the Top Layer. Bottom — enter the required mask expansion for the Bottom Layer. Top Tented — if this checkbox is enabled, the mask is closed on the Top Layer for these shielding vias.
Bottom Tented — if this checkbox is enabled, the mask is closed on the Bottom Layer for these shielding vias. Linked — if the Linked option is enabled, the same expansion value is used for both the Top and Bottom layers. From Hole Edge — enable this option to calculate the mask expansion from the edge of the drill hole instead of the edge of the via donut. Stitching Parameters. Board cutouts can also be routed out. This can be done manually or automatically by the software. A Board Cutout in the first image, with a Route Tool path defined in the second image.
As well as the Board Shape, you also should define a placement and routing boundary around the edge of the board. Alternatively, this can be done manually by placing objects on the keepout layer. Objects placed on this layer define a no-crossing-allowed boundary for components and routing. Typically you want objects such as components and routing to be a certain distance from the edge of the board; this distance can be controlled by setting the applicable routing and component placement design rules.
You can also define other routing and component keepout areas for mechanical objects, such as screw heads or other mounting requirements. A keepout boundary defined by placing standard line objects on the keepout purple layer. Defining the Board Shape in Altium Designer. Using Altium Documentation. The default Board Shape in a new PCB document is a rectangular shape 6 inch x 4 inch, or mil x mil, or 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. End-user machines can be configured to connect to this server in order to check for and download the updates.
We recommend you backup any important information in the Altium Designer installation directory prior to uninstalling. These updates can only be applied to a Winter 09 installation of Altium Designer. Service Pack 1 Build 8. Service Pack 2 Build 8. Service Pack 3 Build 8. These updates can only be applied to a Summer 08 installation of Altium Designer.
Service Pack 1 Build 7. The following updates can only be applied to an existing Altium Designer 6 installation. Updates are non-cumulative meaning that before any update can be installed, the version immediately prior to it has to already be installed for example, 6. Each downloads includes a setup program that is used to install the update.
The below library downloads are deemed to be 'frozen libraries'. The content of these ZIPs was built at the time of the launch of Altium Designer 10, and will not be updated.
The below downloads are deemed to be 'frozen'. These ZIPs were built at the time of the launch of Altium Designer 10 and may not include the same set of examples and reference designs as what is now available in the Content Store.
All Altium Designer releases from Summer 08 onwards include all available output generators. For prior versions, the generators available for download are listed in the following collapsible sections:. Offline Installation of Altium Designer. Using Altium Documentation. You must be signed into AltiumLive.
You may need to sign out of AltiumLive and then sign back in again to see the button. Once the initial request has been approved, you will always be able to have access to the corresponding Offline Installer for each existing version of the software, as well as new versions as they are released. Just select the version of Altium Designer required, and the button will update accordingly.
Each version of the software has its own dedicated installer and therefore requires a dedicated offline installation package.
Clicking the Advanced button will open the Advanced Settings pop-up window in which proxy-settings can be specified. These settings are only needed for the online installer if applicable for that installation environment.
They can be ignored as part of the offline installation. Click to expand an area for greater control over sub-functionality available. Platform Extensions offer extended functionality to the core platform. Each platform extension is a dedicated package of core platform functionality that has been 'brought out' of the platform and delivered in the form of an extension.
By delivering this functionality as an extension, Altium can deliver updates to that core functionality without having to release an update to the entire platform itself. Click to enable functionality at the parent level to quickly enable all of its child functionality too. Importing Preferences from a Previous Version or Major Release After installing and launching your new version of Altium Designer, the Import settings dialog will open in which you are given the opportunity to import preferences from the most recent previous installation at startup.
Preferences can be imported from any individually installed version instance of Altium Designer installed builds of AD10 or later , or any of the following pre-AD10 major releases of the software: Summer 09, Winter 09, Summer 08, and Altium Designer 6. The benefit of importing at initial startup is getting the working environment looking exactly the way it was set up in the previous installation. Importing preferences at a later stage will only 'restore' a subset of this environment.
Note that the offline installation does not check for updates or new extensions regardless of the status of the Altium Connection setting.
