采用程序跟踪方案解密PLD／PAL（GAL）

A Programmatic Tracing Scheme Adopted in De-Secrecy of PLD/PAL(GAL)

介绍一种通过对输出状态的跟踪实现对ＰＬＤ／ＰＡＬ（ＧＡＬ）解密的方案，给出采用ＰＡＳＣＡＬ语言和８０８８汇编语言混合编程的测试软件功能结构及编程方法。

This paper introduces a de-secrecy scheme of PLD/PAL (GAL) through therealization of tracing output states and also suggests the testing software functional structure andprogramming method using PASCAL language and 8088 complilation language in mixingprogramme'
