通过将 RS 触发器的输入 和 绑定为互补值,可以构建一个只有一个输入的 触发器。 要设置为 '1',只需在输入上放置 '1';要设置为 '0',只需在输入上放置 '0'。 0x03 JK Flip-Flop(JK 触发器) JK 触发器是一种在 RS 触发器中不被允许的输入 被允许的触发器。 当两个输入都处于高电平状态时,JK 触...

latch的最大缺点就是没有时钟端,和当前我们尽可能采用时序电路的设计思路不符。 latch是电平触发,相当于有一个使能端,且在激活之后(在使能电平的时候)相当于导线了,随输出而变化,在非使能状态下是保持原来的信号,这就可以看出和flip-flop的差别,其实很多时候latch是不能代替ff的 1.latch对毛刺敏感 2.在ASIC中使...

Assume that you want to implement hierarchical Verilog code for this circuit, using three instantiations of a submodule that has a flip-flop and multiplexer in it. Write a Verilog module (containing one flip-flop and multiplexer) namedtop_modulefor this submodule. ...
原文链接:verilog实现双边沿触发器Dual-edge triggered flip-flop 最近在做HDLBits,做到双边沿触发器,觉得还挺有意思的,记录一下。 verilog不支持同时触发上边沿和下边沿,因为FPGA中只有单边沿触发器,没有双边沿触发器这种器件。 所以,posedge clk or negedge clk是无法综合的。 always @(posedge clk, negedge clk)...

create a 4-to-1 multiplexer (not provided) that chooses what to output depending on sel[1:0]: The value at the input d, after the first, after the second, or after the third D flip-flop. (Essentially, sel selects how many cycles to delay the input, from zero to three clock cycle...
