本文以TH55磁芯板为例,介绍使用计算机在专用测板机上模拟存贮器工作的边界条件和信息布局方式检测磁芯板的原理和方法,作为检测结果。TH55磁芯板确定的可靠工作域为:驱动电流变化±7%,选通时域≥50ns,e_1′和e_0′信号差值≥10mv。这样的检测数据及其检测方法正是目前国内某些高速、大容量磁芯存贮器中确保可能运行的必要条件之一。 In this paper, TH55 core board, for example, introduces the use of computers in a special board machine simulation memory boundary conditions and information layout of the core board principle and method of detection as a test result. TH55 core board to determine the reliable work area: drive current changes ± 7%, gating time domain ≥ 50ns, e_1 ’and e_0’ signal difference ≥ 10mv. Such test data and testing methods are just one of the necessary conditions for ensuring the possible operation in some high-speed and large-capacity magnetic core memories in China at present.
