• Then a comparison is made according to their characters and the application scope of each method is determinate . from that we get the whole scheme of design for testability of dspc50 , which is using boundary scan to improve the board - level testability of the chip and using full - scan in designing the nuclear circuit to reduce the difficulty of testing the chip
  在此基础上得到dspc50的可测性设计的整体方案，即采用边缘扫描设计提高芯片在板级的可测性，同时用全扫描思想设计芯片核心电路，以降低芯片本身测试的难度，即将芯片的全扫描设计包含入边缘扫描系统。
• From the view point of the foundation of dft ( which includes the testable measure of gate - level circuits , the testable and controllable measure of functional - level , the flow and methodology of dft and so on ) , the author introduce some common testing technology such as scan and bist in modern times . especially the boundary scan technology has been widely adopted in the dft of vlsi . with the special controller , the testing vector could be scanned to the corresponding ports of inner cores from the testing input ports , and the response could also be shifted to the testing output ports
  本文从可测性设计的基础理论出发（包括门级电路的可测性测度、功能级上的可测性和可控性、可测性设计的流程和方法等） ，介绍了现代常用的可测性技术，比如：扫描技术、内嵌自测试技术等，特别是边缘扫描技术已经广泛地应用到vlsi的可测性设计之中，它通过特定的控制器，从相应的测试输入端口将测试向量扫描至芯核所对应的管脚，再将结果从相应的测试输出端口扫出。
• In the logic design , the fundamentals and characteristics of ieee std . 1149 . 1 specification and usb protocol are introduced first of all . according to altera ’ s fpga cyclone , it analyzes the architecture and jtag instructions of boundary scan test ( bst ) . then the dissertation analyzes how to program cyclone device and offer the scheme of the design which is realized in verilog hdl by modelsim and quartus ii software
  在接口逻辑设计中,首先分析ieee1149 . 1标准和usb协议,理解边界扫描测试和usb数据传输的工作方式,然后针对altera公司的fpga器件cyclone ,通过分析它的边界扫描测试结构和各种jtag指令,研究它的编程过程和编程特点,并提出设计方案。
