与LS-83机配套的器件约有80多个品种、品种多、数量少、如果采用传统的每个品种编写一个测试程序的方法,程序编制工作量大,时间长,很难满足生产急需,因此开发了用学习法生成功能测试码的方法.该方法的特点是编写一个通用性强的测试程序,通过对合格样品的学习,获得被测器件的真值表,再利用此真值表对被测器件进行测试,中间无需人工干予,大大提高了编制程序的效率和可靠性。经过对LS-83机配套器件的测试和装机实调表明,此方法是行之有效的.一、功能测试码生成的方法1.人工分析法.这种方法是用人工分析电路的逻辑关系来推出真值表.适用于中、小规模的电路;耗时多,效率低,容易出现考虑不周的情况,在中、大规模电路中,人工分析困难多.
With the LS-83 machine supporting the device about more than 80 varieties, variety and quantity is small, if the traditional method of writing a test program for each species, the programming workload, a long time, it is difficult to meet the production needs, Therefore, a method of generating functional test code by learning method is developed.The method is characterized by compiling a universal test program, obtaining the truth table of the device under test through the study of qualified samples, and using the truth table The device under test is tested, without manual intervention in the middle, which greatly improves the efficiency and reliability of programming. After the LS-83 machine supporting device testing and installation of real tune shows that this method is effective.First, the function test code generation method 1. Artificial analysis method.This method is to manually analyze the logic of the circuit to The introduction of truth table. Suitable for medium and small scale circuits; time-consuming, low efficiency, prone to ill-considered situation, in large-scale circuits, manual analysis and more difficult.
