设计序列检测器连续检测串行二进制码,只要出现连续的“101”,即输出 1,否则输出 0。写出该序列检测器的摩尔型状态机VERILOG 代码,给出完整代码,并尽量不报错

设计一个简单的Moore型状态机(Verilog代码)用于检测连续的"101"序列,我们可以使用有限状态机(FSM)。以下是一个基本的Verilog代码示例:
```verilog
module binary_sequence_detector (
input [2:0] bin_input, // 3位输入,假设代表二进制数据
output reg detected, // 输出信号,0 或 1
input reset // 重置输入
);
// 定义状态变量和转换条件
typedef enum {IDLE, COUNT_1, COUNT_2, DETECTED, NOT_DETECTED} State;
State state;
reg [1:0] count; // 计数寄存器
// 状态机转换函数
always @(posedge bin_input or posedge reset) begin
if (reset) begin
state <= IDLE;
count <= 0;
end else begin
case(state)
IDLE: begin
if (bin_input == 3'b101) begin
state <= COUNT_1;
count <= 1;
end else begin
state <= NOT_DETECTED;
end
end
COUNT_1: begin
if (bin_input == 3'b0) begin
state <= COUNT_2;
count <= 2;
end else begin
state <= NOT_DETECTED;
count <= 0;
end
end
COUNT_2: begin
if (bin_input == 3'b0) begin
state <= DETECTED;
detected <= 1;
end else begin
state <= NOT_DETECTED;
count <= 0;
end
end
default: begin
state <= NOT_DETECTED;
count <= 0;
end
endcase
end
end
endmodule
