DIRECT DISPLAY OF WGL AND STIL WAVEFORMS

DFTView is a product capable of making debugging and analysis of ATPG, Simulation and ATE test files much easier. DFTView, combines the waveform viewing technology of SpringSoft’s Verdi/nWave and the industry standard GTKWave viewer with our powerful vector translation technologies to provide a powerful graphical visualization, comparison, analysis and debugging tool for DFT and Test Engineers dealing with WGL and STIL files.

The new product will provide DFT and Test Engineers with the following capabilities:

  • Direct waveform display of WGL and STIL files
  • Direct waveform viewing of VTRAN-generated Advantest V93000, T2000, Teradyne Catalyst, FLEX, and J750 test programs, as well as several others.
  • Ability to examine resulting ATE waveforms applied to DUT for corresponding WGL and STIL files.
  • View affects on waveforms from edits to source WGL and STIL files.
  • Supports vector-related portions of 1450-1999, 1450.1 and 1450.6 STIL standards.
  • Supports WGL & STIL syntax for all popular ATPG tools (TetraMAX, FastScan, Modus Test Solution).
  • Extremely fast waveform display and browsing using proprietary compressed database.
  • Point-and-click linking between source WGL/STIL files and waveform display positions, both directions.
  • Source WGL/STIL file editing with automatic RE-GENERATION of new waveforms
  • Partial file loading for large files

Additional planned feature enhancements for the near future include the following:

  • Timing-View only for graphical view of Timing blocks in WGL/STIL files
  • Support for viewing additional vector and test formats on various ATE Enhanced WGL/STIL file syntax checking.
  • User Editor option so you can use your favorite text editor with DFTView

DFTView® WGL/STIL/V93000 VIEWER

DFT Waveform Viewer

DFTView® works in conjunction with VTRAN’s WGL and STIL canned readers. It is launched from the command line with a source file name (WGL/STIL/V93K) and some optional parameters. It first reads the source file and translates it into an event database for the Waveform tool. It next launches the Waveform tool to display the event database, and simultaneously creates a Text Edit window containing the source file and a collection of action buttons. From here the user can (1) view/edit the source file, (2) Regenerate the display after any edits,( 3) save the edited source and (4) adjust the display to show the waveforms corresponding to a Vector location identified by the cursor position in the text editor.
