摘　　要：针对数字逻辑课程教材中的一处错误,提出使用Digital仿真软件进行测试的改进方案。分析表明:Digital仿真软件能用于组合逻辑电路与时序逻辑电路的测试;其不仅可使用真值表实现测试,还可用测试语句构建大规模的复杂测试用例,更适用于数字逻辑课程教学中设计题目的测试。进一步与Logisim软件比较表明:Digital软件测试功能更强,波形观察方便,更有助于实验和测试;考虑了电源和接地、外接端子均为双向连接,Digital软件所构建和仿真的电路更加符合实际;其RAM器件类型更多,有助于仿真完整的计算机系统。据此提出,在数字电路和计算机组成原理等硬件课程教学中推广使用Digital软件。In view of an error in the textbook of digital logic,an improvement scheme for testing using digital simulation software is proposed.The analysis shows that the Digital simulation software can be used to test both combinational circuit and temporal logic circuit.In addition to using tables to implement tests,statements can be used to construct large-scale complex test cases,fit for the testing of design tasks in the teaching of digital logic courses.Compared with Logisim,Digital logic simulation software is stronger in testing performance.It is convenient in observing waveform,facilitating both experiments and tests.Given that power supply,ground and external terminals are all bi-directional connected,the circuits built and simulated by Digital are more realistic,and more types of RAM devices help simulate the complete computer system.Thus,it is suggested to widely use digital software in teaching hardware courses such as digital circuits and computer composition principles.
