The Company

D4T Systems is a new start up company founded in the Netherlands in 2009. The company finds its origin in the semiconductor world where the founders has been working for many years. From the profound expertise of the founders and co-workers in the test technology domain, a new and innovative way of working for analog testing was defined. In august 2009, D4T Systems was founded and the company started to develop tooling to reduce the ever growing test cost, especially in the analogue domain. 
D4T Systems closes the gap between analogue test and analogue design by exploiting the synergy between design knowledge and test knowledge. D4T focuses on developing advanced test architectures and structures for analogue and mixed signal IC design. Our way of working provides a faster and higher quality test development cycle by using pre-silicon test validation. With D4T Systems the customer will get more value out of his test architecture since we thoroughly balance on-chip and off-chip test methods and design optimisation techniques. Therefore, the customer will get more opportunities for design-in wins, validation, trimming and robustness over lifetime.

Mission

Reducing test cost and improving time to market for the analogue/mixed-signal IC manufacturer is key in all our efforts. D4T Systems wants to provide a full solution for testing analogue/mixed signal chips. Original test tools will be used and developed to validate and automate the test benches early in the design cycle and to directly interface to the tester platforms.

Vision

We believe that analogue design and test must go hand in hand to cut development costs and test costs. Closing the loop between tester platform and design environment is an important driver for minimizing these costs and to improve product quality. Only new test tools incorporating both design environment and tester can challenge todays advanced analogue circuit test requirements. 

Management and Founders

Leon van de Logt has a MSc. degree in Applied physics - Semiconductor physics from the University of Technology Eindhoven, The Netherlands. In 1996 he started to work in audio engineering for medical healthcare where he worked on hearing aid improvement.  In 2000, Leon continued his career in the semiconductor/electronics business where he worked as a research scientist in the Philips Research labs. In this position his responsibilities included test innovation and test implementation for a variety of consumer and automotive products. In 2006 he joined NXP semiconductors from the Philips spin off. In his position he was responsible for the improvement of analogue testing for volume production and he had a leading role in the test innovation program in NXP Semiconductors. Next, he joined the University of Technology, Delft as researcher. Leon is holding more than 10 patents in the field of digital and analog testing.
In 2009 he initiated the foundation of D4T Systems as a new start-up and is currently Director of the company.

Vladimir Zivkovic has obtained his graduate electrical engineering degree in microelectronics at the University of Nis, former Yugoslavia in 1994 and PhD degree at the Faculty of Electrical Engineering at the University of Twente, Netherlands in 2001. During his academic career, he has been involved in the research and teaching activities in both analog and digital integrated circuit design and test automation, acquiring his PhD in the field of Hardware-Software Codesign Test.
His corporate experience begun at the National Semiconductor BV, the Netherlands, where he has been carrying out the duties as an IC designer on DECT applications within the research and development group of the company from 2001 until 2004. From 2004 until 2009, he held a position of a Senior DfT architect at Philips Research (subsequently transformed to NXP Semiconductors). His main responsibilities at that position included  applied research and innovations in the area of DfT and test automation for mixed-signal circuits, as well as consultancy and deployment of innovative methods within business units of Philips/NXP Semiconductors.
Vladimir is currently the co-owner of D4T systems. He is also an author of a number of scientific articles published in international IEEE journals including IEEE Design&Test of Computers and Microelectronics Journal as well as in a number of conferences and workshops, including DATE, ETS, VTS and IMSTW.
