Verilog Examples - Clock Divide by 2 A clock Divider has a clock as an input and it divides the clock input by two. So for example if the frequency of the clock input is 50 MHz, the frequency of the output will
divn # (.WIDTH(26), .N(50000000)) u0 ( .clk(CLOCK_50), .rst_n(KEY[0]), .o_clk(clk_1) ); divn所寫過的萬用除頻器,由於DE2提供的clock是50MHz,但電子鐘只希望每秒變化一次,所以要除頻剩下1Hz,所以要將50MHz除50M,經過計算,這樣需26位才夠,所以傳進26與50000000。 divn.v / Verilog ...

always@(posedge clk or negedge rst_n) begin if(!rst_n) o_clk<=0; elseif(cnt<1)//0 o_clk=0; else//1 o_clk=1; end 利用計數器產生新的clock,當計數器是0時,輸出1,當計數器是1時,輸出0。如此就完成duty cycle為50%的除2除頻器電路。 當然我可以將兩個always寫在一起,不過好的Verilog ...
