    Altium Designer 6.3:新功能介紹 (Whats New in Altium Designer 6.3) Part.2

    Altium Designer 6.3:新功能介紹 (Whats New in Altium Designer 6.3) Part.2 

    New - Traditional Chinese localization support


    Altium Designer has in-built support for detecting and working in the language locale of the Windows installation.
    Supported languages include French, German, Japanese and Simplified Chinese -
    all of these have been extensively reviewed and updated.
    New to Altium Designer 6.3 is language localization support for Traditional Chinese,
    allowing the dialogs, menus and hints to be presented in that language.
    Set the Localization options in the Preferences dialog.

    New - PADS ® Library Importer

    A new importer has been added to the Import Wizard for importing PADS ® footprint (Pattern) libraries.
    ASCII library files up to PADS PowerPCB ® version 2005 (SP0) can be imported.


    Improved - OrCAD ® Importer

    The OrCAD ® importer now fully supports importing OrCAD ® design components that include simulation data.
    Importing of both simulation-ready schematics and schematic libraries is supported.

    New - PADS ® /OrCAD ® Importer

    Designers moving from legacy systems, such as an OrCAD ® schematic
    + PADS ® PCB editor combination can now easily transfer their valuable libraries and design files into Altium Designer.
    The new importer, accessed via the Import Wizard, imports the OrCAD ® schematic symbols
    and PADS ® footprints (Patterns), adding them to a new Altium Designer Library Package
    ready for compiling into an Altium Designer integrated library.

    The importer also supports importing OrCAD ® schematics and PADS ® PCB documents
    in a single operation to create an Altium Designer PCB project.

    This importer provides a straight-forward and robust methodology
    for managing the transfer of legacy designs into Altium Designer.

    Figure 9. The Import Wizard can import design and library files for various design tools.


    New - Slice PCB Tracks

    A tool that helps strengthen Altium Designer's general editing capabilities is the new Track Slicer.
    The Track Slicer provides an easy mechanism for cutting one or more track segments into two.
    Use the Track Slicer to slice one or more tracks on the current layer, or all layers.
    To use the Track Slicer:

    • Choose Slice Track from the Edit submenu (press E to display),
      then move the mouse over existing tracks for a visual indication of which tracks are to be cut.
    • Press the SPACEBAR to lock the Slicer to vertical/horizontal/45 degrees.
    • Press the , (comma) . (full stop) / (slash) or M keys to select the segments on the left side,
      right side, both sides, or to not select any segments.
    • Press the TAB key to configure the Slicer.
    • Press the ~ (tilde) key for a full list of interactive shortcuts.

      Figure 10. Use the Track Slicer to break track segments into two, press Tilda (~) to see the full range of options.

      New - Subnet Jumpers Feature
      One of the great strengths of an FPGA-based design is that the routing challenge
      can be moved from the PCB to inside the FPGA, potentially resulting in fewer routing layers and a simpler,
      cheaper and more reliable PCB.
      For this to be a reality the design system must support both PCB-driven and FPGA-driven pin swaps,
      with full synchronization between the PCB and FPGA designs - Altium Designer provides this high-level of support.

      The best way to exploit this advantage is to route the board in an iterative process -
      escape routing out of the FPGA, then routing incoming signal buses toward the FPGA.
      Once the incoming and outgoing routes are near each other
      it is a straightforward process of performing interactive or automatic pin swaps
      on the FPGA escape routing to de-tangle the connection lines, ready to complete the routing.

      With the new subnet jumper feature you no longer need to manually complete the short routing segments.
      Selecting Add Subnet Jumpers from the Autoroute menu will detect any direct (horizontal, vertical, diagonal)
      connection line shorter than the specified distance,
      then automatically add a track segment of the correct width to complete the route.

      And, since the reality is that design does not happen in a simple, linear fashion,
      you have full support to remove the subnet jumpers when you need to re-adjust the FPGA pinouts
      and perform further pin swaps, to again de-tangle the connection lines.
      Use the Remove Subnet Jumpers command to remove the jumpers, and Add Subnet Jumpers to recreate them.


    New - PCB Selection Tools

    Selection is a core function in the designer's editing toolset, being used constantly during the design process.
    New selection tools in the PCB editor greatly simplify the process of building up a selection set.
    The new selection features can be accessed from the Selection submenu (press S to display) and include:

    • Select Touching Rectangle - any object touched by the selection rectangle will be selected.
    • Select Touching Line - any object touched by the selection line will be selected.
    • Hold the SHIFT key after choosing the command to add to an existing selection set.

      Figure 12. Press S to access the new Select Touching Line and Touching Rectangle commands.


    New - STEP (3D File Format) Export

    STEP, the STandard for the Exchange of Product model data is becoming a preferred standard for ECAD to MCAD data exchange.
    Altium Designer 6.3 includes a new STEP export capability, generating a 3D STEP format file
    ready for import into your preferred mechanical CAD system.

    Figure 13. Export the board in the STEP format, and import to your preferred mechanical CAD tool.


    New - Signal Integrity Examples

    New examples demonstrating the use and power of Altium Designer's Signal Integrity analysis capabilities have been added.
    They include examples of Altium Designer's support for:

    • Signal Integrity analysis of a design using differential pairs.
    • Signal Integrity analysis of a design with a programmed FPGA -
      correct pin models are automatically applied to the FPGA to support the chosen I/O type,
      I/O standard, slew rate and drive strength.


    Improved - Differential Pair Interactive Router

    Today differential pairs is the preferred method of managing the integrity of high-speed signals.
    Interactive differential pair routing has been improved in Altium Designer 6.3 by the addition of:

    • Improved gathering of signals in the pair - pad exits automatically center with a short straight+diagonal route,
      control the behavior by positioning the cursor.
    • Detailed Heads Up information, including current delta (difference in routed pair length)
      and applicable Delta in design rules.

      Figure 14. Improvements to the differential pair interactive router give neater and more efficient differential pair routing.


    New - PCB Layer Sets


    A typical board design could include 8 signal layers, 4 plane layers and 10 mechanical layers,
    as well as the top and bottom silkscreen and ancillary layers, such as solder and paste masks.
    Layer sets are an ideal way of managing the display of this large number of layers.

    PCB layer sets can be defined in the Layer Sets Manager dialog (Design » Manage Layer Sets menu).
    Any number of layer sets can be defined, and each can include any of the layers available in the board design.

    To toggle the workspace to display a different set of layers, use the Layer Set control at the bottom left of the workspace.
    The popup menu will automatically present your current list of Layer Sets.
    Include the & character in the Layer Set Name to define the following character as an accelerator key.

    Figure 15. Define Layer sets in your board, and use them to quickly switch between different sets of displayed layers.


    New - PCB File Versioning

    To support the introduction of new features, such as slotted holes in PCB pads, the PCB file format has changed.
    As part of this release an intelligent file versioning system has been introduced, where, going forward,
    all future releases will be able to intelligently handle PCB files that have a newer format than the format created by that release.

    This release also supports more detailed warnings about potential design changes caused by file format or feature enhancements,
    such as the via-to-polygon connection warning that occur when an older version file is opened in Altium Designer 6.3.

    Figure 16. Details of file version support is automatically reported when an older format file is opened.


    New - Managing Uninstall Information

    Altium Designer updates are performed via the internet,
    using a patching technology that applies updates to the Altium Designer installation files.
    To ensure that you can uninstall any of the updates that you have applied,
    backup copies of all modified files are stored on your hard drive.

    These backup files can be removed if required, open the License Management page (DXP » Licensing),
    expand the applied update and click the Remove Uninstall Info hyperlink.
    Note that update information is removed separately for each update,
    allowing you to manage which updates are still uninstallable and which are not.
    This process is not reversible, once you have removed the uninstall information
    you will no longer be able to uninstall that update.

    Figure 17. Use the Remove Uninstall Info feature to remove the backup files from your hard drive.
