【hdlbits_Exams/review2015_fsmseq】用LFSR 写更简单一些

module top_module ( input clk, input reset,// Synchronous reset input data, output start_shifting); reg [3:0] d; always @(posedge clk) begin d<= {d[2:0],data}; if (reset) begin start_shifting<=1'b0; d <= 4'b0; end else if ({d[2:0],data} == 4'b1101) start_shifting<=1'b1; endendmodule
