Jx5 microprocessor ’ s testing structure comprises built - in self - test ( bist ), boundary scan and internal scan
Jx5微處理器的測試結構由bist 、邊界掃描和內部掃描三部分組成。 -
There are four subsidiary factories under the head office, set up the production department, the technological department, domestic business department, international business department, count the department of the wealth, quality testing department, because the close cooperation of the office and factory, has formed as a organic whole managing the organization export - orientedly of marketting one ' s own products, in order to cater to the customer ' s demand, self - built labour protection glove professional factory ' s family is 9600 square meters, process hides 20000 of workshop, dispose one produce special machine 620 of glove, make its forming 3 production lines, guarantee product quality effectively and deliver on time, promote and produce increasing with sale rapidly, annual amount of production rise to 1, 600, 000 harvest from 150, 000, annual revenue in foreign exchange created rise to 22 million dollars by 2 million dollars, on pay because it last 6 million yuans taxes and profits, contribute after making some for country
總公司屬下有四個分廠，設置生產科，技術科，國內業務科，國際業務科，計財科，質檢科，由於科室與工廠的緊密配合，形成了自產自銷為一體的外向型經營機構，為迎合客戶的需求，自建勞保手套專業廠戶9600平方米，製革車間20000平方米，配置一套生產手套的專機620臺，使之形成三條生產流水線，有效地確保產品質量和按時交貨，促進生產和銷售迅速增長，年生產量由15萬打增加到160萬打，年創匯額由200萬美元增加到2200萬美元，上交稅利由5萬元增加到600萬元，為國家作了一些貢獻。 -
And more than 70 % hardware are tested during microcode self - test since the execution of micro program can cover other data paths. boundary scan is designed according to ieee1149. 1, and some other instructions such as degug, runbist are provided to support internal fault testing, online debugging and built - in self - test besides the several necessary insructions. internal scan is implemented by partial scan, through this the boundary of logic component and user - cared system registers can be selected to be scanned
Bist用於測試cpu的微碼rom ，其它ram則利用微碼rom中的微程序進行測試，而微程序的運行則可以順帶覆蓋其它數據通路，從而使高達70 %的硬體得到測試;邊界掃描按ieee1149 . 1標準設計，除必備的幾條邊界掃描指令外，還提供了debug 、 runbist等指令以支持內部故障測試、在線調試及內建自測試;內部掃描採用部分掃描策略，選擇邏輯部件的邊界及用戶關心的系統寄存器進行掃描，從而實現了硬體邏輯劃分，方便了后續的測試碼產生和故障模擬，並為在線調試打下了基礎。 -
The advantages of the two methods are combined together in the pseudo - random current injection testing method, which improves the efficiency and correctness of the test, and which is much more operable, thus it is very applicable in built - in - self - testing of analog and mixed signal circuits in system chips
偽隨機注入電流測試法結合了兩種方法的優點，提高了測試的效率和正確性，實現時簡單易行，非常適合於系統晶元中對模擬及混合信號電路的內建自測試。
