以下是一个米利型状机 module fsm (input clk,acc,brake,reset, output [1:0] speed ); reg [1:0] state; reg [1:0] next_state; localparam STOP=2'b00; localparam LOW=2'b01; localparam MEDIUM=2'b10; localparam HIGH =2'b11; //状态转换 always@(posedge clk or posedeg reset) if(reset) state=STOP; elsestate=next_state; //次态计算 always@(*) case(state) STOP: if (acc && !brake) next_state=LOW; else next_state=STOP; LOW: if (brake) next_state=STOP; else if (acc) next_state=MEDIUM; else next_state=LOW; MEDIUM: if (brake) next_state=LOW; else if (acc) next_state=HIGH; else next_state=MEDIUM; HIGH: if (brake) next_state=MEDIUM; else next_state=HIGH; endcase //输出逻辑 assign speed=state; endmodule
选项：

A:正确;
