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"*)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 1. 2. 3. 4. 5. 6. 7. 8. “最大计数”位置应给定一个值,CNT将在0~最大计数区间内循环+1。注意...
(*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
(* MARK_DEBUG="true" *)input wire [7:0] din0, (* MARK_DEBUG="true" *)input wire [7:0] din1, input wire [7:0] din2, input wire [7:0] din3, (* MARK_DEBUG="true" *)output wire [7:0] crc_o ); parameter [7:0] poly = 8'b0000_0111; (* MARK_DEBUG="true" *)...
为被关注的仿真时刻添加标签(Mark),方便来回观看; 通过添加标尺可以查看信号事件间距、周期信号频率、统计信号事件等功能; 将常用的状态信号、总线信号、某个用例调试用的信号等保存成do文件,即将当前波形界面的元素保存下来,方便波形重现; 每个人看波形的习惯和方式会有不同,找到自己习惯的方式就可以了; ...
2019-12-06 20:39 −Xilinx Vivado 提供了上板后的FPGA逻辑分析,信号视图显示等功能。 需要注意,上板后查看信号需要重新综合,并且需要耗费一定的片上布局布线资源。 1. 添加debug信号 可以对模块端口或者wire 变量进行debug信号提取,只要在verilog代码前面添加:(* MARK_DEBUG... ...
As expected, we didn’t see nearly the performance improvement on Windows that we did on Unix. Average speed improvement was probably 3% or less on our benchmark suite. However, the 64bit simulator is still useful when you’re working on a very large design that won’t compile or run...
