boundary in-circuit test 中文意思是什麼
boundary in-circuit test
解釋
邊界內電路測試-
In this paper, we combine the standard modules realize the boundary scan of estarl and also expand it to the test of internal circuit. this structure can save the i / o port of the chip and simplify the testing program
本文結合標準模塊設計實現了estar1的邊界掃描結構，並進行了擴展，應用到晶元內部測試，節約了測試i / o口消耗，簡化了測試過程。 -
So here introduces a new method - the combination of boundary scan with deltascan, in which deltascan is applied to do short and open test in ict, so that the number of vectors used to test circuit short and open in boundary can be eliminated. all vector test, including boundary scan test, need to create test vectors
任何邏輯元件的矢量測試，包括邊界掃描測試，都必須先生成測試矢量，然後用這些測試矢量作為輸入端的激勵信號，因此測試矢量是矢量測試的基礎，測試矢量生成方法的難易程度和測試矢量數目是邊界掃描技術能否在實際中應用的關鍵。 -
This thesis discusses the realization of pcbs ict production through a concrete example in which boundary scan technology is applied, and presents a new method to improve the test speed, based on the analysis of boundary scan circuit and means for vector creation. he applys boundary scan ( bs ) to boundary - scan device on the board where bs features by easy vector creation, need less knowledge of the device
本文結合一個具體電路板在線測試實現，首先討論了在ict中，採用邊界掃描元件測試技術實現在線測試生產；並在分析歸納各種測試方法的基礎上探索一種新的改進方法，即將deltascan技術與邊界掃描技術相結合以減少測試矢量，增加測試速度的一種實用方法。 -
The main contents are as follows : the structure of mixed - signal circuit which newly - defined in ieee1149. 4 std is analyzed in detail, especially anolog boundary module and test bus interface circuit. on the basis of mixed - signal boundary scan technology, a scheme of mixed - signal boundary - scan test system is presented and the hardwares are implemented, including the controller and display unit
