    Altium Designer 6.8:新功能介紹 (Whats New in Altium Designer 6.8) Part.3


    New - Device Sheets

    Implementing design reuse as a strategy in your development cycle makes a lot of sense
    - faster turnaround times and higher levels of quality are more easily achieved
    without having to recreate designs from scratch.

    Much of the hard work is essentially eliminated,
    and engineers are allowed instead to develop and fine-tune the real improvements,
    rather than spend considerable time on locating, rewiring, and verifying circuitry.

    New Device Sheets allows you to incorporate this powerful capability into your development cycle
    and help bring your designs to market faster.
    Device Sheets begin with creating and storing verified circuitry to quickly build-up resources of proven designs
    that can be used at any time.
    They are then readily accessible to save time without having to search through folders on the hard drive
    or open individual schematics to find what is needed, or verify that it works.

    Sharing proven designs in this manner means that a development team can have resources at their fingertips
    without the effort involved in researching a solution to see that someone else has already come across it.

    Device Sheets are stored as normal schematic documents in special Device Sheet Folders.
    They are placed and referenced in your project, similarly to a simple component.
    Once the project is compiled, Device Sheets are included in the project hierarchy
    and can be distinguished from schematic documents by a different schematic document icon in the Projects panel.

    Figure 19. Device Sheet Folders contain all of the Device Sheets available across your projects.
    When Device Sheets are placed in your project,
    they are given a unique schematic document icon to differentiate them from normal schematic documents.
    One Device Sheet can be used across multiple projects.

    Creating and Placing Device Sheets in your Project


    A Device Sheet can be any normal schematic document including schematic documents with sheet symbols.
    You must first declare a Device Sheet through DXP » Preferences » Schematic » Device Sheets under the Schematic folder.
    Device Sheets, by default, are read-only unless you change this through Preferences.
    Once editable, any changes are saved back to your source document.

    Placing Device Sheet Symbols in your Project

    Once Device Sheets have been saved and their location declared,
    Device Sheet Symbols representing your Device Sheets can be placed in your project
    using the Place » Device Sheet Symbol command.

    After the Device Sheet Symbols have been placed in your schematic documents,
    they act in the same way as standard sheet symbols but have different graphical properties indicating
    that they reference a Device Sheet.


    Figure 21. The recycle symbol indicates this sheet symbol references a Device Sheet
    and can be reused within and across projects.

    New - Board Level Annotation

    Designs that use repeated channels or device sheets create a challenge in terms of
    how to manage repeated component designators.
    New Board Level Annotation provides a method of ensuring that logical components remain uniquely identified
    and in sync through all phases of multi-channel design and when using Device Sheets.

    Logical components remain related to their physical implementations, and can be easily reannotated,
    or default naming schemes changed.
    When launched from Tools » Board Level Annotate in the Schematic editor, Board Level Annotation is performed.
    A new compiled documents view that shows the physical names of the components opens up.
    Display options can be enabled to show the source (logical) component names in superscript should you require them.


    Figure 22. Filtering Options in the left pane will filter out components that you don't want to see.
    Undesignated components are shown here with question marks.

    The annotation scheme can be specified through the Board Level Annotate Options dialog
    which is launched from this dialog.
    New Editor and Compiled Documents tabs in the main design window offer views for both source and compiled projects.
    For multi-channel designs, there is one compiled document per channel.
    If there are no channels in your design, there is only one compiled document per schematic document.


    Figure 23. The Editor tab is the only tab you will see when you first open a project.
    You have to compile your project to view Compiled Documents.

    Improved - Sheet Entry Editing

    Appreciating that you need efficient editing capabilities for faster turn-around on designs,
    placing and moving sheet entries has been made more intelligent.
    Sheet symbols no longer need to be pre-selected prior to placing, and sheet entries
    can be easily moved from symbol to symbol in the schematic document.


    Figure 24. Visual indicators help you identify whether you are making correct placement or not.
    Blue (top image) indicates correct placement while gray (bottom image) indicates incorrect.

    The appearance of sheet entries can be further customized with the Sheet Entry dialog.
    New graphical shapes for sheet entries have been added and sheet entry texts can also be tailored.


    Figure 25. Here we see how text can be customized. On the left side,
    the font is enlarged and set to Bold and Italics while the font on the right side the default font is used
    with the text style set to show the bus prefix (in this case without any width).

    New - Move Selected Object with Arrow Keys

    Perhaps the single thing most needed for productivity in any design environment is
    to have repeatedly-used commands or capabilities readily available.

    Controlling objects in both the schematic and PCB editors has been enhanced to allow you to select
    and move them by increments using only the arrow keys.
    Simply select one or more objects in a document, then hold CTRL key
    and press the Arrow keys to relocate the selected objects.

    Improved - Schematic Library Editing


    Editing the designator and comments in components in schematic libraries can now be done on the fly.
    A new option to make these visible and interactively editable must be enabled first
    - launch the Library Editor Workspace dialog by right-clicking in the workspace and then selecting Options.
    From here you can change the font, move, rename or edit them.

    New - Publish to PDF

    A new way to setup and generate output jobs to PDF for both PCB
    and schematic has been introduced with Publish to PDF.
    Publish to PDF allows you to build custom PDF documents from the OutputJob Editor.
    Any number of Schematic, OpenBus, PCB and PCB3D outputs including all printable Assembly Drawings,
    Documentation Outputs and Fabrication Outputs can be combined together into a single document.

    Figure 27. You can build custom PDF documents from a number of different source files
    that can be configured to include both logical and physical representations of your design
    as well as different page sizes and orientations.

    PDF bookmarks are created for each output and all of their corresponding components, nets, pins and ports.
    Output Job Files, through their portable nature can be defined once
    and used in multiple projects allowing you to reuse PDF Setup and Schematic Print Properties.
    This process can also be automated using scripts without having to manually select items in the OutputJob Editor.

    New - Protect Locked Objects

    Preventing schematic objects on a schematic sheet from being inadvertently moved
    or edited is ensured with a Locked property through the Schematic Inspector.


    Figure 28. Protect Locked Objects is enabled through the schematic preferences
    (Tools » Schematic Preferences)

    New - SIMetrix/SIMPLIS ®

    Altium Designer 6.8 now supports Catena software's popular SIMetrix/SIMPLIS ® circuit simulation package.
    SIMetrix/SIMPLIS is a combination of two independent circuit simulators: SIMetrix,
    a SPICE-based simulator with numerous enhancements including extra models for power transistor devices,
    and SIMPLIS, a fast simulator that uses piecewise linear approximations
    and includes useful analysis modes for switching power supply circuits.
    A license to run SIMetrix/SIMPLIS (release 5.3j or higher) is required to use this feature.

    Altium Designer supports SIMetrix/SIMPLIS in three main ways:

    • Direct simulation from Altium Designer in SIMetrix/SIMPLIS
    • Importing models from the SIMetrix/SIMPLIS model library
    • Exporting schematics containing simulation models to SIMetrix/SIMPLIS format.
      Before you begin you will need set up the location of your SIMetrix/SIMPLIS installation
      by selecting DXP » Preferences, then clicking on Simulation » SIMetrix Interface.
      This preferences page lets you choose whether to view the results of your simulations
      in SIMetrix/SIMPLIS or in Altium Designer.


    Figure 29. Simulation-SIMetrix Interface options
    allow you to decide how you would like to display your graph results.

    Two new menu commands will then appear:
    Design » Simulate » SIMetrix and Design » Simulate » SIMPLIS.

    Most simulation models from Altium Designer's libraries can be used in SIMetrix/SIMPLIS,
    but you can also import models from the SIMetrix/SIMPLIS model library into Altium Designer.

    Altium Designer lets you mix and match the different model types.
    If you have multiple models for a component that have been tuned for each simulator,
    then you can attach them all to the component. Whenever you run a simulation,
    Altium Designer will choose the best one for your target simulator.

    To export your Altium Designer schematic to SIMetrix/SIMPLIS format,
    launch File » Export File to SIMetrix. This is particularly useful
    when you want to run many simulations in SIMetrix/SIMPLIS or use multi-step analysis modes
    that are not directly supported in Altium Designer.
    To get started with this feature, refer to a new application note Using SIMetrix SIMPLIS Circuit Simulation
    For more information on SIMetrix/SIMPLIS, refer to the Catena website.


    Figure 30. To run a simulation in SIMPLIS, select the Design » Simulate » SIMPLIS command.
