💭 写在前面:本章将理解 RS/D 锁存器的概念,了解 RS/D/JK 触发器的概念,使用 Verilog 实现各种锁存器 (Latch) 和翻转器 (Flip-Flop),并通过 FPGA 验证用 Verilog 的实现。 📜 本章目录: Ⅰ. 前置知识回顾 0x00 锁存器(Latch) 0x01 RS 触发器(RS Flip-Flop) 0x02 D 触发器(D Flip-Flop) ...
看别人的吧:Verilog code for D flip-flop - All modeling styles (technobyte.org)Verilog: T flip flop using dataflow model - Stack Overflow 我倾向于认为Verilog的<=没那么强; 它可以偷偷地把 q <= ~((enable & reset) | q_); 换成if嘛。 1. 叫modeling style不叫coding style. 2. if (!con...

out=in1 & in2; endmodule 结构式的描述∶在这层次中模块是由逻辑闸(Gate Level)连接而成,在这层次的设计工作就好像以前用描绘逻辑闸来设计线路一样。例1中的AND是Verilog的基本元件 (primitive),是Verilog语言预先定义好的函式。 数据流式的描述∶ 它是一种模拟组合函式的方法。当任何输入有所改变时,输出会...
Hi guys, I am very much new to verilog and I have been trying to replicate an LUT-FF pair with a multiplexer to select the output from either
In other cases, the flip flop/register only has the SDATA wired (nothing into D data in). I don't understand the difference in this case to just wiring it in the "normal" way, and I would like to understand if there are any differences. Since I am on the novice level, I'm al...
触发器(Flip-Flop):时钟触发,受时钟控制,只有在时钟触发时才采样当前的输⼊,产⽣输出。 锁存器: 由电平触发,⾮同步控制。在使能信号有效时锁存器相当于通路,在使能信号⽆效时锁存器保持输出状态。 (锁存器对输⼊电平敏感,受布线延迟影响较⼤,很难保证输出没有⽑刺产⽣;触发器则不易产⽣⽑...
