Astronavigation-based PROM evaluation method and system

The invention discloses an astronavigation-based PROM evaluation method. The method comprises the following steps of: 1, evaluating a component level, wherein the evaluation of the component level comprises storage unit evaluation, storage unit-storage associated characteristic evaluation and component-level function and performance analysis; 2, evaluating a board level, wherein the evaluation ofthe board level comprises basic function verification, port time series verification, power supply biasing test, power on/power off test and CPU matching test; and 43, evaluating a programmer, whereinthe evaluation of the programmer comprises program output stability analysis and resistance consistency analysis after programming. The method is capable of comprehensively evaluating PROM devices and has an important meaning for PROM evaluation. 本发明公开了种基于宇航应用的PROM评价方法，所述方法包括如下步骤：步骤：对元器件级进行评价；其中，元器件级评价包括存储单元评价、存储单元-存储关联特性评价和元器件级功能性能分析；步骤二：对板级进行评价；其中，板级评价包括基本功能验证、端口时序验证、电源拉偏测试、上下电测试和与CPU匹配测试；步骤三：对编程器进行评价；其中，编程器评价包括编程器输出稳定性
