Hierarchical DesignDWW_featrue_image_3

  • Hierarchical Design with unlimited levels is fully supported. Any symbol on a schematic can contain another schematic of arbitrary size. Blocks can be nested to any desired depth, limited only by available memory. Any number of hierarchical blocks can be open for editing at any time. To support a variety of applications, two hierarchical modes are supported: Pure Mode is designed for use in VLSI design and other applications requiring large circuit sizes. In this mode, all instances of a circuit block are identical and editing the internals of one block immediately updates all similar blocks. Interactive simulation is not available in pure hierarchy mode since separate simulation data is not available for the various instances. Physical Mode is intended for use with the DesignWorks simulator or for any designs requiring physical design data (i.e. PCB package names and pin numbers) which may be different among the various instances of an internal circuit.
  • Automatically create ports on a hierarchical block or underlying schematic
  • Hierarchical structure allows you to attach sub-circuits to a part
  • Associate a part hierarchically with a multipage schematic
  • Control hierarchical part descent on an instance basis

DesignWorks provides a number of powerful operations for working with device or hierarchical block symbols and internal circuit definitions. Hierarchy Mode – Three hierarchy modes are available to accommodate different design requirements. “Flat” mode provides the simplest possible structure for smaller designs. “Pure” mode implements a pure hierarchical structure, i.e. each part type is defined only once and all instances of a type are identical. “Physical” mode allows full hierarchical operation, but allows separate attribute data to be associated with each physical instance of a part. Hierarchy Operations – Hierarchical designs can be created “top-down” or “bottom-up”. Attach and Detach commands allow separately created designs to be merged into a single hierarchy, or vice-versa. Internal circuit definitions can be saved with a part in a library or as a separate circuit file. Part definitions can be saved from a schematic sheet to a library. Devices in a schematic can be updated from their original library or from any selected new source.

Netlisting and Report Generation

DesignWorks Professional includes a powerful Custom Report Generator tool for netlist and text report generation. The report format is driven by a “form file” which contains formatting commands and constant text. Form file features allow you to control: Overall report structure, e.g. netlist formats by signal or by device, listings by device for bills of materials, etc. Design, device, signal and pin attributes to be included. Selection of devices or signals to include in the report, by name or attribute value. Selection of attribute fields to be used as sources for power and ground connections. Sorting and merging of lines within the file. Format of each pin connection entry, each line and each page. Hierarchy format, including flattened and hierarchical netlists. Error checking, including checking for missing attribute fields. The package includes 20 or more form files for standard industry formats. These can be used as-is or used as a guide for creating your own formats.

Scripting and Custom Display PanelsDWW_feature_image 4

DesignWorks Professional includes several powerful technologies for scripting and customization. The new JavaScript feature, introduced in version 5, allows full access to all design data and virtually every program function. This means that users or OEMs can create scripts for everything from automating a frequently-used sequence of editing steps to adding sophisticated import/export, data entry or display, analysis or simulation functions. The scripting features are coupled with the ability to display custom panels using HTML. Since these panels are actually an instance of Internet Explorer, you can use the full power of web display technology to display and prompt for data with full access to design data and program functions. This allows for extensive customization of DesignWorks for specific applications.

PDF, DXF and Graphics Export

DesignWorks can save diagrams in the standard PDF (Acrobat)WMF (Windows Metafile) and DXF (AutoCAD) graphics formats. This capability allows you to pass graphics to other programs for plotting, enhancement, or incorporation into other documentation.

  • PDF (otherwise known as Acrobat format) is widely used on the web to store images of printed documents that can be displayed or printed on any type of computer system with close to identical results.
  • WMF is a standard format under Windows for representing graphics objects such as lines, circles, text, etc. This format can be read by many Windows-based graphics and word processing packages.
  • DXF is a format developed by AutoDesk for use with their AutoCAD series of general CAD packages. In addition to AutoCAD, most general drafting packages can read and write DXF.

Searching and Error Checking

The Find tool allows you to interactively locate devices, pins or signals by name, attribute value, error condition or other characteristics. The Find tool is completely scriptable, so you can customize it to do your own searches and analyses. The Report generator tool, in addition to generating netlists and bills of materials, can be used to perform various types of error checking and analysis. This could include checking compatibility of connections, correctly formatted attribute fields, required design information, etc.

Back Annotation

The PCB Back Annotation tool allows device package assignments to be automatically updated from a “was-is” text file created by an external system. Formats supported include Cadnetix (SCICARDS), Douglas, Racal-Redac RINF and XCAD. Pin and gate swaps, and component renaming are supported in flat or hierarchical designs. In addition, the scripting features can be used to read any desired external source, such as a text file, database or web service and apply any changes to design data with full control.
