摘要
本文提出的可编程逻辑器件易测试方法，充分利用了ＰＬＤ本身固有的可编程特点，简化了器件故障诊断的难度；所有延时、逻辑故障全部可以检测，对延时故障和交叉点故障具有诊断功能，故障检测。
An easily testable design scheme proposed in the paper makes full use of the intrinsic programmable characteristic of PLD in itself to simplify the difficulty in diagnosing.All delay faults and logic faults can be detected.Delay faults and crosspoint faults can be diagnosed.The detection and diagnosis are extraordinarily convenient.
