The verilog case statement performs the same function as theswitch statement in the Cprogramming language. The code snippet below shows the general syntax for the case statement in verilog. case(<variable>)<valu
verilog case,if语句情况不全包含会生成锁存器 数字电路中应避免产生不必要的锁存器 Latch 锁存器(Latch)是数字逻辑电路中很重要的一种基本电路,常见的锁存器包括三个端口:数据输入口、数据输出口、使能端。当使能端为高电平时,输入口的数据直接送到输出口,此时输入输出口可以看成是直接连通的;当使能端为低电平...
“随着综合工具的进步,已经不需要讨论if-else 和case的区别了,两者可以等同 ” “Verilog 2001标准(IEEE 1364-2001)第132页: The case item expressions shall be evaluated and compared in the exact order in which they are given. 指出了case是串行有优先级。又: Apart from syntax, the case statement di...
