DFT(Design For Test) Technology
SoC testing is becoming more complicated as processes become more refined, circuit scale increases, circuit operation becomes faster, and much less power is consumed. To resolve this issue, in addition to compressed scan, memory BIST, and boundary scan DFT, we perform high quality testing using various types of DFT technology for improved test quality and yield.
