Current loop#7 Current loop#8 Current loop#9 ncsim: *W,RNQUIE: Simulation is complete. Design Example Let us take a look at how an 8-bit left shift register can be implemented in Verilog without aforloop and then compare it with the code using aforloop just to appreciate the utility ...

repeat (loop_times) begin … end 1. 2. 3. repeat 的功能是执行固定次数的循环,它不能像 while 循环那样用一个逻辑表达式来确定循环是否继续执行。repeat 循环的次数必须是一个常量、变量或信号。如果循环次数是变量信号,则循环次数是开始执行 repeat 循环时变量信号的值。即便执行期间,循环次数代表的变量信号值...

then the hierarchy editor sees the memory_bit and everything below, simulation starts and gives expected result. I've been trying to understand why such a so simple and straight forward thing does not work and what I was doing wrong and, finally, reading the doc...
