// If you want a counter that counts a range different from 0 to (2^n)-1, // then you need to add another rule to reset q to 0 when roll-over should occur. endmodule 知识点:相比我的答案,参考答案更简洁,因为4bit的q最大计数值就为15,可以利用这一点简化代码。 2 Decade counter | ...
2)仅当counter0计数10次(q0==4’d9)时,counter1计数1次,也就是counter0计数10个时钟周期后,下一时钟周期counter1计数,c_enable[1]=1’b1; 3)当counter1计数10次时(q1==4’d9),counter1会保存q1==4’d9十个时钟周期才会变回0,即需要counter0==4’d9才会再次变化。所以counter2有效的时钟周期为coun...
