Verilog语言——序列检测器

设计一个序列检测器，检测器在有“101”序列输入时输出为1，其他输入情况下，输出为0。

module xuliejiance(x,z,clk,rst,state);

input x,clk,rst;

output z;

output[2:0] state;

reg[2:0] state;

wire z;

parameter IDLE='d0,A='d1,B='d2,C='d3,G='D4;

assign z=(state==C&&x==1)?1:0;

always @(posedge clk)

  if(!rst)

          begin

          state <= IDLE;

          end

  else

          casex(state)

            IDLE : if(x==1)

                      begin

                          state <= A;

                      end

            A:    if(x==0)

                      begin

                          state <= B;

                      end

            B:    if(x==1)

                      begin

                          state <= C;

                      end

                    else

                      begin

                          state <= G;

                      end

            C:      if(x==1)

                      begin

                          state <= A;

                      end

                    else

                      begin

                          state <= G;

                      end

            G:      if(x==1)

                      begin

                          state <= A;

                      end

          default:state=IDLE; //缺省状态为初始状态。

          endcase

endmodule
