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
本文從可測性設計的基礎理論出發（包括門級電路的可測性測度、功能級上的可測性和可控性、可測性設計的流程和方法等） ，介紹了現代常用的可測性技術，比如：掃描技術、內嵌自測試技術等，特別是邊緣掃描技術已經廣泛地應用到vlsi的可測性設計之中，它通過特定的控制器，從相應的測試輸入埠將測試向量掃描至芯核所對應的管腳，再將結果從相應的測試輸出埠掃出。
