我们熟悉的逻辑函数化简方法是卡诺图法。卡诺图法具有简单、直观的优点，但当变量数目达到或超过5个以后，卡诺图将变得很复杂，甚至无法使用。而列表法对于解决多变量逻辑函数化简具有显著的优越性，并且这种方法有严格规则和步骤，便于计算机操作。列表法最早由Quine和Mcluskey提出，因此该法又称为Q-M法。许多数字电路课本上给出了便于手工计算的列表法，但并没有给出实际利用计算机语言实现的方法。-We are familiar with the logic function is the K-map Simplification Act. K-map method is simple, intuitive advantages, but the number of variables to or more than five after the K-map will become very complicated, can not even use. The list method for solving the simplification of multi-variable logic function has significant advantages, and this method has strict rules and procedures to facilitate computer operation. List method was first proposed by Quine and Mcluskey made, so the method is also known as QM method. Many digital circuits textbook gives a list of easy hand-calculation method, but did not give the actual use of computer language approach.
