Source III, Inc.

VTRAN Vector Translation Tool

With nearly 25 years of field-proven success, VTRAN™ offers the most cost-effective, full-feature solution to creating EDA and ATE test programs from simulation and ATPG vectors. Whether you need to translate VCD or EVCD simulation dump files into a test program for one of the popular device testers, or you are taking ATPG-generated vectors in WGL or STIL format to a tester, VTRAN™ provides the most reliable and lowest-cost option available today. If you are using an in-house tool for this, VTRAN™ can save your valuable in-house resources, time and money while at the same time bringing many powerful vector processing features to bear on solving your vector translation problems. Source III’s technical support staff becomes an extension to your design and test groups to ensure your success. You get a proven, reliable product with a full-time technical staff to support it at a fraction of the cost of just one in-house engineer. No other tool on the market can offer the level of scope, features, performance, support and low-cost that VTRAN™ is able to offer. Recently released supporting tools, such as the Vtran User Interface which guides you thru the translation process, and DFTView our visualization and validation tool, further simplify the translation process.


  • Blazing Speed – VTRAN™ can translate GigaByte files in minutes. Text/Script batch compiler gives the user full control over the process, or optionally Vtran User Interface provides a simple guided method for performing translations.
  • For most tester interfaces, VTRAN also includes a ReadBack module which provides a re-simulation verification path from VTRAN-generated test programs to a Verilog or VHDL testbench.
  • Short learning curve and Excellent Documentation – VTRAN™ learning time as low as 2-6 hours for many translation applications. Vtran™ User’s Guide, example translations and Application Notes all available online, in addition to the graphical user interface.
  • Outstanding Technical Support – Source III is highly responsive to all customer needs. New features are often added within days to meet customer needs. We provide you with personalized technical support.
  • Low Cost!! – VTRAN™ is the lowest cost, full-feature, validated vector translation program on the market.
