Design of interface converter circuit for programming instrument gpib port to general parallel printer port 接口與通用并行打印接口轉(zhuǎn)換電路的設(shè)計
After analyzing and digesting register - based interface circuit designed by predecessor , this paper designs register - based interface circuit of speed test module and programs instrument 在分析消化了前人設(shè)計的vxi總線寄存器基接口電路的基礎(chǔ)上,設(shè)計了測速儀模塊的寄存器基接口電路,編寫了儀器驅(qū)動程序。
Basic black - box testing and white - box testing are successfully carried out . in white - box testing , the statement coverage and branch coverage are achieved ; static analysis and dynamic analysis are also implemented . the static analysis mainly used to generate flow graph while the dynamic analysis serves program instrument , technique realization object , subprogram and the detailed coverage and the calculation of operation time of the documents 原型系統(tǒng)實現(xiàn)了基本的黑盒和白盒測試,其中白盒測試實現(xiàn)了語句和分支覆蓋;實現(xiàn)了匯編測試的靜態(tài)分析和動態(tài)分析,靜態(tài)分析主要是生成程序的流程圖,動態(tài)分析主要是利用程序插樁技術(shù)實現(xiàn)語句和分支覆蓋率及在多個測試用例驅(qū)動下的綜合覆蓋率的計算和運行時間及內(nèi)存使用情況的統(tǒng)計。
