题解 | #异步复位的串联T触发器#

思路

写出2个TFF即可，TFF关系为 Q*=Q^T;

代码

`timescale 1ns/1ns
module Tff_2 (
input wire data, clk, rst,
output reg q  
);
//*************code***********//
    reg data_1;
    always @ (posedge clk or negedge rst) begin
        if (!rst)
            data_1 <= 1'b0;
        else
            data_1 <= data ^ data_1 ;
    end
    
    always @ (posedge clk or negedge rst) begin
        if (!rst)
            q <= 1'b0;
        else
            q <= data_1 ^ q;
    end

//*************code***********//
