定义状态机当前状态为state ,次态为next _state; 输入a,输出b, 则下列为Mealy状态机的写法是:
A.always@(posedge clk) case (state ) 0:next_state<=1; 1:next_state<=x;#B.always@(posedge clk) case (state ) 0: if(a==0)next_state<=1; else next_state<=x; 1:next_state<=x;#C.always@(posedge clk) case (state ) 0: if(state==0)next_state<=1; else next_state<=x; 1:next_state<=x;#D.以上都不对第6题:
