💭 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) ...
//设计文件源代码 module D_type_flip_flop(d,r,clk,q ); parameter WIDTH = 1; input r; input d; input clk; output reg [WIDTH-1:0] q; always @ (posedge clk or negedge r) begin if (~ r ) q <= {WIDTH{1…
同步复位逻辑会在时钟信号的某个边沿到来时,根据复位信号的状态来重置D触发器的输出状态。 Verilog实现 以下是一个同步复位D触发器的Verilog实现示例: verilog module sync_d_flip_flop ( input wire clk, // 时钟输入 input wire rst, // 同步复位输入(高电平有效) input wire d_in, // 数据输入 output re...
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...

The D Flip Flop! (Source: Wikipedia) Notice in the picture above there is a pin on the top of the device labeled S. This is known as the Set pin. On the bottom of the device there is a pin labeled R. This is known as the Reset pin. Additionally, on the right side of the dev...
