vivado中保存波形数据

在测试代码中添加以下代码：

    `define dump_level 10  
    //module dump_task;  
    initial begin#1; //延迟1ns记录，方便与其他仿真动作协调  
        `ifdef VCS_DUMP //Synopsys VCD+格式存储  
        $display("Start Recording Waveform in VPD format!");  
        $vcdpluson();  
        $vcdplustraceon;  
        `endif  
         
        `ifdef FSDB_DUMP //Synopsys fsdb格式存储  
        $display("Start Recording Waveform in FSDB format!");  
        $fsdbDumpfile("dump.fsdb");  
        $fsdbDumpvars('dump_level);  
        `endif  
         
         
        `ifdef NC_DUMP//cadence 格式存储  
        $recordsetup("dump","version=1","run=1","directory=.");  
        $recordvars("depth=6");  
        `endif  
         
        `ifdef VCD_DUMP//工业标准VCD格式存储  
        $display("Start Recording Waveform in VCD format!");  
        $dumpfile("dump.vcd");  
        $dumpvars('dump_level);  
        `endif  
    end
