首先第一步,需要把想要观测的信号标记出来,即mark_debug,有两种mark_debug的方法,我用verilog写了一个简单的流水灯程序,只有几行代码,如下: module main( input clk, input rst, output reg [7:0] led ); (*mark_debug = "true"*)reg [23:0] counter; always @(posedge clk) begin if(rst) begin ...
(*mark_debug ="true"*)reg [12:0] hcnt; (*mark_debug ="true"*)reg [12:0] ycnt; (*mark_debug ="true"*)wire hsync_pre; (*mark_debug ="true"*)wire vsync_pre; assign hsync_pre = (hcnt >= HBLANK && ycnt <= VSIZE-1) ?1:0;//(ycnt==VSIZE && hcnt<=HBLANK-1)?1:0...
(*mark_debug="true"*)outputreghsync_ot,(*mark_debug="true"*)outputreg[15:0]data_out);assignclk_out=clk_60m;localparamHSIZE=16;localparamHBLANK=2;localparamVSIZE=16;localparamVBLANK=20;/*行场同步信号生成*///延迟
2. 变量x为4’d0执行A语句,为4’d1执行B语句,为4’d2执行C语句,否则执行D语句。 3.循环计数 代码如下: (*mark_debug = "true"*)reg [5:0] CNT; always @ (posedge CLK or negedge RST) begin if(!RST) CNT <= 1'b0; else CNT <= (CNT==最大计数-1) ? 1'd0 : CNT + 1'd1; end...
