    New - Hardware Accelerated Graphics Engine

    Altium Designer's PCB editor has a new Hardware Accelerated Graphics Engine.
    This engine provides a substantial increase in drawing speed over the current GDI-based graphics engine,
    providing smooth, real-time graphics within the PCB editor.
    The redraw speed is effectively instant, even on the largest PCBs.

    The new graphics engine is built around the Shader Model 3.0 technology supported by Microsoft DirectX 9.0c.
    Shader Modeling is a technique where the code for rendering the objects displayed
    by an application is executed on the Graphics card Processor Unit (GPU), instead of on the main CPU.

    Traditionally the graphics card is treated as a dumb pixel painter,
    where the application code first renders the image as a bitmap in memory
    and then passes all of the pixel data from the main CPU to the GPU.

    Using Shader modeling technology the rendering code is executed on the GPU,
    the application code issues instructions to the GPU to render a particular type of object,
    supplying a minimal set of data such as object locations, color, lighting, and so on.

    In the case of Altium Designer's PCB editor, this means that rather than passing a large number of pixels
    that when rendered paint a track object on the screen, the GPU is programmed to know how to draw a track -
    Altium Designer simply passes location coordinates, width and color information.

    The new Hardware Accelerated Graphics Engine will:

    • Provide drawing speed improvements in the order of 20 times over GDI.
    • Remove the impact of polygons on drawing speed.
    • Provide smooth panning and scrolling, at all zoom levels.
    • Maintain drawing and panning performance for the largest of boards.
    • Be thoroughly tested and benchmarked on a wide variety of graphics cards.
    • Work in harmony with the existing graphics engine, allowing the user to switch between them as needed.
      Note that the new graphics engine requires a graphics card that supports DirectX ® 9.0c and Shader Model 3.0.
      Use the following links to learn more about Shader technology:
      http://en.wikipedia.org/wiki/Shader
      http://www.microsoft.com/whdc/winhec/partners/shadermodel30_NVIDIA.mspx

    New - Copper Pour (Polygon) Management System

    A standard design technique on today's dense,
    high-speed boards is to use all spare board space as reference planes, filling them with regions of solid copper.
    These regions of copper, known as copper pours, are created by placing polygons.
    It is not uncommon for a multi-layer board design to include 50 or more polygons.

    The new Polygon Manager provides a powerful control center for reviewing and managing all of the polygons on a board.
    The Polygon Manager is launched from the Tools » Polygon Pours submenu.
    The Polygon Manager not only provides a high-level view of all polygons on the entire board, with it you can:

    • Name and rename each polygon.
    • Set the pour order of polygons.
    • Perform actions on selected polygons, such as repour or shelve (hide from display and DRC).
    • Add and scope design rules for selected polygons.

      Figure 1. Polygon manager allows you to review and manage all polygons on the board.

    Improved - Polygon Connectivity and Speed

    Appreciating the importance of working with polygons in the board design process,
    Altium Designer 6.3 delivers enhancements to polygon connectivity and polygon pouring speeds.
    It offers:

    • Full support for connectivity between polygons and vias.
      Vias can be directly connected or thermally connected to polygons.
      Opening an older format file will warn of potential connection changes.
    • Polygon pouring speed has been substantially improved.
    • Polygon graphics performance has been improved.
      This benefit is delivered in both the existing and new graphics engine.

      Figure 2. Control the via-to-polygon connection using Design Rules.
      Here the GND via is directly connected, while the VDDA_E net vias are thermally connected.

    New - Place and Gather Multiple Traces

    Altium Designer 6.0 saw the addition of Smart Dragging -
    a powerful feature for easily moving existing track segments
    while maintaining the correct angles to connected segments.
    Smart Drag also incorporated a simple yet elegant feature for extending an unconnected track end -
    dragging on the end vertex adds a new segment, correctly angled away from the existing segment.

    This Smart Drag capability has been substantially improved in Altium Designer 6.3
    by the addition of support for multiple tracks.
    This allows a group of tracks to be selected and then extended as a single entity.
    You can use successive drags to continue to add new segments.

    Taking the Smart Drag concept a step closer to becoming a bus routing tool is the new Place » Multiple Traces command.
    Using this command you can start with an unrouted component
    and effectively pull the routing out of the selected component pads.
    The multiple traces are then automatically gathered together, as shown in Figure 3.
    Simply move the cursor around as you place the multiple traces to explore various gather options.
    These multi-trace capabilities from pads or track ends represents the first stage
    in the development of a Bus Routing strategy.
    Keep the following tips in mind when working with the Multiple Traces command:

    • Rather than selecting component pads one by one,
      hold the Ctrl key as you click and drag a rectangle to select.
      Holding Ctrl limits the selection to the pad objects only, rather than selecting the parent component.
      This also works with the Select Touching Line and Select Touching Rectangle commands.
    • Press the Tab key to open the Bus Routing dialog, where you set the Bus Spacing
      (track center to track center separation).
    • Alternatively, use the , (comma) and . (full stop) shortcuts to interactively decrement
      and increment the bus spacing, in steps of the current snap grid.
    • Press the \ (Backslash) to change the end alignment (once the first set of segments has been placed).
    • Press the ~ (Tilda) key for a list of interactive shortcuts.

      Figure 3. Use the Place » Multiple Traces command to start from selected pads in an unrouted component.
      Move the cursor to explore gathering options.

    New - Slotted and Square Holes in PCB Pads

    Altium Designer 6.3 supports slotted and square holes in PCB pads.
    Slotted and square holes are defined in the redesigned PCB Pad dialog,
    giving you immediate visual feedback on the design of the pad.
    Support for slotted/square holes includes:

    • Round ended (NC routed) slotted holes.
    • Square (punched) holes.
    • Plated or un-plated slotted and square holes
    • Separate drill files (NC Drill Excellon format 2) are generated for each hole kind (round, square, slot),
      as well as for plated and non-plated (up to 6 different drill files).
    • Full support for power plane connections and clearances.
    • Updated PCB Pad dialog, giving instant visual feedback on the pad design.

      Figure 4. Create slotted or square holes in your PCB.

    New - Version-controlled Libraries

    Version control systems provide an ideal method for managing and controlling access to electronic documents.
    Altium Designer 6.3 brings library management and version control together
    with the new version-controlled database libraries.

    Version-controlled database libraries are an extension of Altium Designer's database libraries,
    a type of library where components are placed directly from a company database.

    The new version-controlled database libraries offer:

    • Ease of use; all Altium Designer library components are placed directly from the Libraries panel -
      component data is read directly from the company database,
      with the referenced symbol and footprint being placed from the version control repository (Subversion).
    • When you click to place a component from the Libraries panel,
      the component status is checked and if the symbol or footprint are not the latest
      then they are automatically updated from the repository.
    • A new Library type,* .SVNDBLib has been added.
      The SVNDBLib library file is added to the Libraries panel and components placed
      directly from there (the same as the standard database libraries,* .DBLib).
    • A new Wizard has been added to help restructure libraries for version control,
      converting multi-component libraries into single model (symbol, footprint, 3d model) files,
      ready for adding to the Subversion repository.
      Storing each model in its own file is more appropriate for version-controlled sources.
    • Altium Designer models that are stored in the repository can be edited directly from
      Altium Designer and the updated model checked back into the repository.
    • A detailed physical difference check can be performed between revisions of a model,
      directly from within Altium Designer.

      Figure 5. Use the Storage Manager to manage version-controlled models.
      Adding model files to the SVN repository and managing the structure of files
      and folders in the repository is performed in an SVN client, such as TortoiseSVN.
      For more information on working with Version-Controlled Database Libraries,
      refer to the application note included with the software, [Working with Version-Controlled Database Libraries].

    New - Create Offline Library from Database Library

    Altium Designer's Database Libraries are an ideal choice if you want your Altium Designer components
    to be tightly coupled to your company database.

    There will be situations where direct database access is not desirable though,
    for example when the design needs to leave your company site,
    or you have contract designers and you prefer they work from secure integrated libraries.

    With Altium Designer 6.3's new Offline Integrated Library Maker wizard you can achieve this.
    Use the new Offline Integrated Library Maker to compile an integrated library directly from a database library,
    or a Subversion-based database library.

    The wizard will build Altium Designer schematic and PCB libraries,
    create a new library package and compile the portable integrated library -
    creating an integrated library for each table in the database.
    Select the Tools » Offline Integrated Library Maker from the DBLib or SVNDBLib menus to run the wizard.

    Figure 6. Create a portable offline library from your company database library.

    New - IPC Compliant Board-level Libraries

    Altium's Library Development Center is in the process of developing IPC-7350 series footprint libraries
    (current surface mount footprints are created to IPC-SM-782).

    • These footprints will be supplied in both PCB footprint library format (.PcbLib)
      and also used across the manufacturer-based integrated libraries (
      .IntLib)
      included with Altium Designer, where appropriate.
      Check the \Altium Designer 6\Library\Pcb\IPC-7530 Series folder to see which footprints are currently available.
    • As specified by IPC-7351 and where applicable,
      each component will have three footprint variants denoted Nominal, Least and Maximum.
      Footprints are named with the appropriate letter at the end of the name.
      The default for each component is the Nominal (_N) footprint,
      this can be changed to the Least (_L) or Maximum (_M) in the Component Properties dialog in the schematic editor.
    • As specified in IPC-7351, each footprint includes an Assembly layer (Mechanical13)
      and Courtyard layer (Mechanical15).

      Figure 7. The new IPC-7350 series footprints come in 3 variants (Nominal, Least and Maximum),
      and include assembly and courtyard details.

    New - IPC® Compliant Footprint Wizard

    The new IPC® Compliant Footprint Wizard creates IPC-compliant component footprints.
    Rather than working from footprint dimensions,
    the IPC Compliant Footprint Wizard uses dimensional information from the component itself,
    in accordance with the algorithms released by the IPC. |

    In accordance with the IPC standard it also supports three footprint variants, tailored to suit the board density.
    With its initial release the wizard supports BGA, QFP and SOIC footprints.
    Support for other package kinds will be added in future Altium Designer updates.

    Figure 8. Quickly create IPC-compliant component footprints from the component dimensions
    in the new IPC Compliant Footprint Wizard.
