debugging online 中文意思是什麼
-
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。 -
This structure not only achieves the purpose of hardware logic partition but also makes it convenient for the generation of test stimulus, fault simulation, and online debugging. furthermore, we make internal scan share the test access port, so the pin ’ s cost which brings for test is reduced
此外為減少晶元引腳開銷，我們還把內部掃描和邊界掃描集成在一起，使其共用測試引腳，降低了因測試而帶來的晶元引腳開銷。 -
And the online debugging of the software based jiag are accomplished
然後實現了基於jtag的軟體在線調試。
