Popular VTRAN™ Translations

VTRAN™ Release 10.1 Translators

The 10.1 Release of VTRAN™ supports numerous translation paths between popular simulation, ATPG and tester vector formats. Included in this is support for the handling of scan data, as well as multiple timing sets. Scan data support is particularly important for vector files created by many of the scan insertion, BIST and other ATPG programs on the market today.

The following matrix summarizes the availability of canned readers and writers for some of the more popular translation paths. The Support column indicates, for cycle-based formats, whether VTRAN™ supports scan, loop or repeat syntax. For those testers that do not indicate scan or loop support, VTRAN™ will automatically flatten any of these structures that may have been in the input file before translation. VTRAN™ can translate any format for which a Reader module exists to any format for which a Writer module exists. Please note that this list is not exhaustive, it merely highlights some of the more popular formats - see VTRAN™ User's Guide Appendix C, D and E for a complete listing.

VTRAN™ provides many powerful facilities for performing these translations which can vary significantly in complexity and user involvement. Translations from cycle-based formats like WGL, STIL (IEEE Standard 1450-1999) or TDL_91 to either simulator or tester formats typically are straightforward and require very little input from the user.

On the other hand, for translations from event-based formats like Verilog VCD/EVCD format to simulators/testers, the user must provide information about pin directions and timing since this information is not contained explicitly in the VCD vector file itself. Translations from VCD to any of the cycle-based formats (all of the tester formats) will also require the use of one of the ALIGN processes, or the TEMPLATE_CYCLIZATION process to cyclize the event-based data.

For additional information on these, and other format translations, together with examples, see the INTERFACES directory which can be downloaded from the Download web page. Also, check our Application Notes web page.

Customer Quotes

  • Intrinsix Uses VTRAN® to Speed Vector Translation Flow "I had one customer who used VHDL for RTL, Verilog for gate level simulation, and sometimes used EPIC tools. Getting vectors into the various formats was a nightmare. VTRAN® made the translation process easy and seamless. Plus, WGL or STIL for the test group. Support from Source III has also been quite impressive. In one case, they wrote a bug fix for me in under a day." John Weiland Intrinsix Consultant  
  • We use VTRAN® to translate WGL or TDL vectors to Teradyne J750 and Flex format. The produced patterns work fine and adaptation to a new device pinout can be done easy and quickly.
  • We currently use VTRAN for translating WGL, EVCD and VCD vectors to be used on various Verigy and Teradyne platforms. Their feature set has allowed us to perform vector manipulation instead of writing Perl scripts. Their support has been very responsive and they are open to additional features on future releases.
  • Sanera Utilizes Full Featured VTRAN® to Convert Functional and ATPG Vectors "We chose VTRAN® because it can handle multiple simulation file formats (including VCD and WGL) from a single tool. VTRAN's commands are easy to use. The flexibility in pin mapping, masking outputs, and generating scan-based vectors proves to be tremendously helpful. And most of all, Source III provides excellent, fast response to our support needs. This helps us to get things moving very quickly - making good solid progress." Ken ChenTest Engineering Manager
  • Source III VTRAN® tool has been very efficient to translate VCD, WGL, and STIL vectors to Teradyne UFLEX and Verigy 93000 ATE formats. Their response to add or implement new features as per customer needs is impeccable and steadfast. I would highly recommend using this tool to any test engineer for vector conversion
  • VTRAN® is currently our tool of choice for converting MS digital test patterns between various logic simulation formats and WGL/STIL. Our experience with Source III has been positive and their support is extremely responsive and timely.
