Abstract :
RPCT is one of the key design and test issues since ATE(Automatic test equipment) channel consumption is increased dramatically for SoC(System-on-Chip) development. A new efficient RPCT test method is proposed which is based on test data compression using a burst clock controller. The proposed method considers the connection of internal/external clock signals and makes the control block using the existing DFT(Design for Test) circuitry. The experimental results show that the proposed method can drastically reduce test cost, ATE dependence and testing complexity.
