时序险象基本判据
BASIC CRITERIA OF SEQUENTIAL HAZARD
-
摘要: 本文利用几个定义和限制,得到了一外部激励x,n个状态变量电位异步时序电路的任一状态的一般逻辑表达式特性方程.将此方程与状态表结合,导出了产生时序险象时的状态变量数和稳定状态数所满足的条件;给出了对时序险象研究特别有用的基本判定法则.

Abstract: By using some definitions and restrictions, an ordinary logical expression-the characteristic equation for one external urge and an orbitrary state of n-state variables potential asynchronous sequential logical circuit is obtained. The characteristic equation combines express with the state table, the conditions satisfied by the state variable numbers and stable state numbers when happen sequential hazards are deduced. The basic laws which are particularly used to study sequential hazards are given. -
