Abstract

DVS Digital Video Systems designs, manufactures and markets digital video interface and storage systems ranging from standard TV up to HDTV (high definition television). A new board is designed and developed which contains all modifications for JTAG boundary scan test. This test procedure is standardized by the IEEE by the Joint Test Access Group (JTAG) and is also named boundary scan test. The test procedure is implemented with a simple serial bus (JTAG bus) which is distributed between all JTAG testable components. The core logic for testing is realized internally in the chips and allows the access to all IO pins via dedicated shift registers. The board is part of the ProntoVideo digital video disk recorder developed and manufactured by DVS. The reason for JTAG test is that for complex and high density electronic boards an analysis of errors (soldering errors for example) by hand costs a lot of time and is very expensive. Testing the board via JTAG allows a quick location of errors and reduce the manufacturing time drastically.

The project had a duration of 12 months and cost 72 KECU. The payback period is about 2 years, the product lifetime is 4 years, the ROI is 300 %.

As target audience all companies are relevant which develop products in the areas ”electronic engineering”, ”multimedia systems” or ”audiovisual electronics”.
