    Altium Designer 6.9:新功能介紹 (Whats New in Altium Designer 6.9) Part.2


    New - Jumper Connections

    New jumper feature allows you to set a jumper connection
    (physical connection between pads but not using tracks on PCB, a separate wire instead)
    between pads on a component. This is especially useful when crossing tracks on a single layer board.

    Jumper connections define electrical connections between component pads
    that are not physically routed with primitives on the PCB.
    These are especially useful on single layer boards,
    where a wire is used to jump over tracks on the one physical layer,
    or even as complex as designing with a 'crossover' switch.

    The Design Rules Checker will not report jumper connections as unrouted nets.


    Pads within a component can be labeled with a Jumper ID value from within the Pad dialog.
    Pads that share the same Jumper ID and electrical net tell the system that there is a legitimate,
    although physically unconnected, connection between them.

    New - Units Toggle


    Many dialogs now feature a units toggle control in the top-left corner
    that will change the units of measurement currently used in the dialog between the metric and imperial.

    Shortcut CTRL + Q can also be used in dialogs where this control is present.
    Toggling units at any time does not affect system accuracy
    as all numerical calculations are carried out at system resolution.

    Improved - Special Strings

    Especially useful for design documentation, special strings act as placeholders for PCB design
    or system-based information and are only populated
    with information when generating manufacturing output data.

    To use a special string on a PCB, place a string object and set its text to be one of the special string names.
    Special strings provide manufacturing records for the software build number of the version of Altium Designer
    that was used during output generation and for the current revision number of the document.

    • .Application_BuildNumber - places the version of Altium Designer on the PCB document
      that the PCB is currently loaded in.
      When generating Gerber output, this string will record the software build
      that the design was created on.
    • .VersionControl_RevNumber - once placed, displays the current revision number of the document.
      Version control must be used for this string to contain any information.
    • .Computer Name - places the name of the machine that the PCB is currently loaded on.
    • .Pattern - displays the names of the component footprints used on the PCB.
    • .SlotHole_Count - once placed, displays the number of slotted holes on the PCB.
    • .SquareHole_Count - displays the number of square holes on the PCB.

    Improved - Publish to PDF

    If you publish a specific set of documents to PDF on a regular basis,
    you can now use a Batch flag to specify your document set and run the Batch Publish to PDF command.
    Batch preferences are saved to the Output Job File.
    You can create multiple Output Job Files with different batch preferences
    for the same project to suit your needs.

    Figure 12. Access the Batch Publish to PDF command from the Tools menu
    or by right clicking in the Output Job Editor and selecting it from the pop-up menu that appears.

    New - Design Refactoring

    Making changes on the fly and restructuring your schematic design is more flexible than ever with Design Refactoring.
    Design Refactoring converts existing Schematic Sheets into Device Sheets,
    and converts Device Sheets into Schematic Sheets.

    Parts can also be converted to ports, and parts can be converted to sheet symbols
    although it's worth mentioning in this instance that the Unique ID isn't maintained
    as one part may be converted into many ports.

    Subcircuits can be moved easily between schematic sheets as well.
    Refactoring of sheets is performed at the Sheet Symbol or Device Sheet Symbol level.
    Design Refactoring automatically maintains synchronization with the rest of your design,
    ensuring that subcircuits in the schematic are always linked to their physical instances
    in the PCB through the maintenance the Unique ID of all subcircuits.

    Found in two convenient locations, Refactoring commands can be launched
    from both the Edit and right-click menu in a schematic document.

    New - Web Updates


    It will now be possible for you to create, manage, and directly access your own account,
    taking advantage of a wide range of future online services.

    The first of these online services, available in Altium Designer 6.9, is the ability to obtain web updates.
    From the Home Page, simply log into your account using your SUPPORTcenter credentials
    (available through your local Altium Sales and Support Center or Reseller).
    Then, use the Check for Updates link to get the latest updates.

    New - FPGA Peripheral Cores

    Expanding your options for peripherals, Altium Designer 6.9 adds support for three new peripheral cores.
    For schematic-based design of your main processor system, all peripherals can be found in,
    and placed from, the FPGA Peripherals integrated library
    (\Program Files\Altium Designer 6\Library\Fpga\FPGA Peripherals.IntLib).

    For a design incorporating an OpenBus System, all components can be found in,
    and placed from, the OpenBus Palette panel.
    Corresponding core reference documents can be found in the Help directory
    (\Program Files\Altium Designer 6\Help).

    WB_USB

    The WB_USB peripheral provides the interface between a processor in the FPGA design
    and an external USB Interface device, for subsequent communications over a Universal Serial Bus (USB).

    The peripheral has been built specifically to interface to the EZ-USB SX2™ device
    (CY7C68001, from Cypress Semiconductor).

    This high-speed (USB 2.0) USB Interface device has a built-in USB transceiver and a Serial Interface Engine (SIE),
    which automatically manages the USB protocol.

    If you are using Altium's Desktop NanoBoard NB2DSK01,
    the USB-IrDA-Ethernet Peripheral Board PB03 features a CY7C68001 device.

    WB_BOOTLOADER

    The WB_BOOTLOADER peripheral provides the ability to automatically load (or bootstrap)
    from serial Flash memory on the Desktop NanoBoard NB2DSK01.

    The device provides the interface between the NB2DSK01'S SPI bus and independent SRAM on the daughter board.
    Provided the device is enabled for boot operation,
    then as soon as the design is programmed into the daughter board FPGA
    (or an external reset is issued if already programmed)
    the content of the serial Flash memory device will be copied into the SRAM.

    The device is configurable in that you can specify where in SRAM the content copied
    from the serial Flash memory is to be written, and the size of the memory involved in the copy.

    The WB_BOOTLOADER can also be used as a standard SPI Controller,
    with an optional interface to a processor in your design,
    enabling the processor to communicate with slave SPI-compatible devices external
    to the FPGA in which the design is running. Operating as an SPI Controller,
    the device is functionally identical to the SPI_W peripheral.

    WB_I2S

    Altium Designer's WB_I2S Configurable Wishbone Audio Streaming Controller is used to facilitate data
    transfers over the inter-IC sound (I2S) bus.
    The I2S bus - developed by Philips as a dedicated serial link for digital audio
    - allows a standardized communication medium for an ever-increasing array of digital audio devices.

    The WB_I2S is an enhanced version of the legacy I2S_W peripheral.
    As part of its configurable nature, it allows you to enable, and define, a much larger hardware buffer.
    With larger FIFO buffers, interrupts can be disabled and simple periodic polling of the state of the
    Transmit and Receive buffers performed instead.

    Additional internal registers are used to store the values for the pointers to the Head and Tail of each buffer,
    enabling you to ascertain how many samples are currently available to be read in the Receive Buffer,
    and how much sample space is available for writing new samples in the Transmit Buffer.
    Like the I2S_W, the WB_I2S provides for transmission and reception of data.
    Unlike the I2S_W however, you can configure the WB_I2S to just transmit data or just receive data.

    Improved - Xilinx EDK Support

    Altium Designer 6.9 now supports the following later versions of the Xilinx EDK (Embedded Development Kit):

    • 8.1 and 8.2
    • 9.1 and 9.2

    New - Context-sensitive C language help

    Altium Designer 6.9 brings with it F1 context-sensitive help support for C keywords and standard functions.
    Simply highlight part of the keyword or function of interest, in the C coding editor,
    to access related information directly in the Knowledge Center panel.

    The information can also be found in the document
    C/C++ Language Reference (PDF檔案)
