C++ SystemC AMS中的跟踪信号问题

我在SystemC AMS中实现了一个正弦波发生器，并希望在特定时间段内可视化其输出。为此，我想创建一个vcd文件。发电机代码和主要功能如下所示。我的问题是vcd文件是空的。我做错了什么

main.cpp：

#include <iostream>
#include "systemc.h"
#include "systemc-ams.h"
#include "sin_source.h"

int sc_main (int argc, char* argv[])
{
    std::cout << "Hello World" << std::endl;

    sca_tdf::sca_signal <double> out1;
    sin_source mySine("sine1");
    mySine.out(out1);

    sca_util::sca_trace_file *tf1= sca_util::sca_create_vcd_trace_file("sine_wave");
    sca_util::sca_trace(tf1, out1, "i'm_sine_1");

    sc_core::sc_start(10, sc_core::SC_MS);
    sca_util::sca_close_vcd_trace_file(tf1);

    return 0;
}

int sc_main (int argc, char* argv[])
{
    std::cout << "Hello World" << std::endl;

    sca_tdf::sca_signal <double> out1;
    sin_source mySine("sine1");
    mySine.out(out1);

    std::cout << "Hello World 2" << std::endl;

    sca_util::sca_trace_file *tf1= sca_util::sca_create_vcd_trace_file("sine_wave");

    std::cout << "Hello World 3" << std::endl;

    sca_util::sca_trace(tf1, out1, "sine");

    std::cout << "Hello World 4" << std::endl;

    sc_core::sc_start(10, sc_core::SC_MS);

    std::cout << "Hello World 5" << std::endl;

    sca_util::sca_close_vcd_trace_file(tf1);

    std::cout << "Hello World 6" << std::endl;

    return 0;
}

我无法重现这个问题。您是否在文本编辑器中打开该文件以检查它是否真的为空

我看到的可能有问题的问题是“以信号的名义（sca_util:：sca_trace（tf1，out1，“I'm_sine_1”）”）-可能您的waveviewer不喜欢它。

也许您可以尝试在systemc ams论坛上问一个问题：尝试将您的信号重命名为不使用任何特殊字符的名称（例如，从中删除撇号）[i'm_sine_1]）。我见过一些EDA工具无法处理类似的事情。重命名信号@rainer不起作用。请查看我的编辑。因此，我上面的代码为您生成了一个正弦波图？您是否使用eclipse/cygwin设置？

int sc_main (int argc, char* argv[])
{
    std::cout << "Hello World" << std::endl;

    sca_tdf::sca_signal <double> out1;
    sin_source mySine("sine1");
    mySine.out(out1);

    std::cout << "Hello World 2" << std::endl;

    sca_util::sca_trace_file *tf1= sca_util::sca_create_vcd_trace_file("sine_wave");

    std::cout << "Hello World 3" << std::endl;

    sca_util::sca_trace(tf1, out1, "sine");

    std::cout << "Hello World 4" << std::endl;

    sc_core::sc_start(10, sc_core::SC_MS);

    std::cout << "Hello World 5" << std::endl;

    sca_util::sca_close_vcd_trace_file(tf1);

    std::cout << "Hello World 6" << std::endl;

    return 0;
}
