一、引言测试系统一般都具有通用性强、测试速度快等优点。但对于数量少、品种多的器件来说,往往编程序时间多于测试本身所需时间,降低了测试系统的有效利用率。本文提出的存贮器测试程序设置了4根电源线、7根控制线、14根地址线、8根输入线和8根输出线,共41根线(如需要也可更多)。对41根线以内不同器件的测试程序,可用联机调试方式(ODT)直接修改系统存贮器中的测
I. INTRODUCTION Test systems generally have the advantages of versatility, fast test speed and so on. But for a small number of varieties of devices, the programming often more time than the test itself, reducing the effective utilization of the test system. The memory test program presented in this paper has four power lines, seven control lines, 14 address lines, eight input lines, and eight output lines, for a total of 41 lines (and more if needed). For testing programs of different devices within 41 lines, the online test mode (ODT) can be used to directly modify the measurement in system memory
