对GAL器件输出逻辑宏单元使用的探讨

Discussions on the Use of Output Logic Macro Cell of GAL Device

探讨了通用阵列逻辑（ＧＡＬ）器件输出逻辑宏单元（ＯＬＭＣ）的配置和工作原理，还探讨了在编写源文件时可能出现的错误及其原因，进而给出了输出逻辑宏单元的使用和管脚设定的规则。

The configuration and the operation principle of the Output Logic Macro Cell (OLMC) of General Array Logic (GAL) device are discussed. Some errors possibly arising in programming a source file and the reasons for causing them are described. Futhermore, the rules for using OLMC and the pins setting of GAL device are presented.
