Along with the development of electronic manufacturing industry, DFT (Design for Testability or Design for Testing) has showed up its importance of guiding the designers to improve the testability of the designed circuit. Against such background, Test / DFT software has also become prominent. Today’s article will give an introduction on two popular test software: TestWay from Aster Technologies and Test Expert Vayo Technology.

TestWay from Aster Technologies

Both Aster Technologies and Vayo Technology are founded by test professionals from electronics industry, and have worked out strong product for PCB test fields.

Aster Technologies, started relatively earlier, goes very deep in PCB test fields and developed its strong test product, TestWay. This board DFT & Test coverage analyzer has established a test structure based on a testability framework. The operating principles of TestWay is to import schematic or layout data and component model libraries, then to perform a topological analysis and symbolic simulation. The resulted topological and accessibility data would be used to check each rule.

TestWay is indeed powerful in providing approaches for DFT and testability analysis, while to conduct the complete set of testing process is still somewhat complicated for engineers and it requires more data import.

Test Expert from Vayo Technology

Vayo Technology has chose another way to its product strategy. Vayo emphasizes more on the intelligence and ease-of-use of software tools. A software should come to ease people’s work and promote efficiency, not to complicate the task.

With 17+ years’ devotion to NPI solution, Vayo Technology has worked out VayoPro – Test Expert software. VayoPro – Test Expert not only stands out in DFT/testability analysis, but highlights intelligence and low complexity, achieving the goal of tool supporting people. Test Expert supports import of all popular CAD data and by intelligently integrating with testability requirements, performs a comprehensive DFT / testability analysis as well as test strategy analysis. The testability report generated by Test Expert provides a rich content with more than 13 categories, including Accessible Net Report, Insufficient Probes (accessible net), Parallel Report, NC Pin List, Unstable Test Point, etc.

 
Comparing with other DFT/testability software, VayoPro – Test Expert comes with those competitive advantages: mask layer validation via extra Gerber data source, virtual nets merge for higher testability, backdrill identification, batch nail offset for flying probe tester, etc.

About Vayo Technoloy

Founded in 2005, Vayo Technology maybe starts relatively late, its core founder members are all technical experts from electronics industry and believes ‘intelligent software brings pleasant work’. With 17+ years’ effort and devotion to NPI/DFT/DFA/CAM software solutions for electronics industry, Vayo Technology’s NPI solution like 3D DFM/DFA analysis, DFX execution system, stencil know-how digitalization, DFT / testability & strategy analysis, SMT specialized CAM tool, visual aids work instruction, board view & fast query, Gerber view & conversion,… has gained worldwide recognition among the electronic industry.

Up to now, Vayo owns 25+ patents and has been recognized by 500+ customers from 20+ countries worldwide. We are proud to announce that VayoPro – Test Expert has been selected by Flex / Venture / Jabil/ Sanmina / IMI / Benchmark / OSI / Katek / Paramit / Intel / GE / Keysight / Intuitive / Bosch and so on.

We have also received some favorable comments from our partners.

“From years of experience with DFT and CAD SW’s, VayoPro – Test Expert is the best. It is fast, accurate and easy to use. Its DFT report is very comprehensible for our customers.” said by David Kim, Test Development Manager from Paramit.

“With VayoPro – Test Expert solution and great support of Vayo team, we could accelerate our product review for DFT (ICT/Boundary).”, said by Tong Chang, Production Associate Manager from Supermicro.

“By introducing Vayo‘s intelligent software tool it is now possible for operators to perform data conversion requiring little skill, while reducing the work time required to one fifth of what it was.” said by Mitsuo Imai, General manager from Fuji.
