    • A multiple input logic gate that is amenable to full testability without the "buried logic" problem of conventional VLSI logic devices and a novel dynamic test method for incresing fault-free production and simplified analysis of sub-chip faults. In one disclosed illustrative embodiment of the logic gate (20) of the invention, the device comprises a replicated, hierarchial arranged group of six two-variable input gates (10) to form a three-variable input gate and two such three input gates and associated logic control structure are provided on a single VLSI integrated circuit chip. Each two-variable input gate (12) is controlled by its own programmed logic array thereby providing a selection of any of the possible 256 Boolean functions for each of the three-variable input gates on a chip. A highly advantageous dynamic test method exploits the regular hierarchial architecture of the inventive logic gate to provide top-down evaluation of each two-variable input gate until the six-gate structure is fully tested. The test method is implemented by clocking the two-variable input gates through their respective sixteen Boolean functions sequentially and displaying a video map of gate output signals which will conform to a specified pattern when the device is fault-free.
    • 一种多输入逻辑门,无需传统VLSI逻辑器件的“埋地逻辑”问题即可实现全面的可测试性,以及一种新颖的动态测试方法,可实现无故障生产和简化分片故障分析。 在本发明的逻辑门(20)的一个公开的说明性实施例中,该器件包括复制的,等级排列的六个双变量输入门(10)的组,以形成三变量输入门和两个这样的三个输入门和 相关联的逻辑控制结构提供在单个VLSI集成电路芯片上。 每个双变量输入门(12)由其自己的编程逻辑阵列控制,从而为芯片上的三个可变输入门中的每一个提供可能的256个布尔函数中的任一个的选择。 一个非常有利的动态测试方法利用本发明的逻辑门的常规层次结构来提供每个双变量输入门的自上而下的评估,直到六门结构被完全测试为止。 测试方法是通过对它们各自的16个布尔函数顺序计时双变量输入门来实现的,并且当设备无故障时显示门输出信号的视频映射,该视频映射将符合指定的模式。
