c++ - systemC 错误 : No instance of constructor "BlackBox ... 等

Question

我试图在 SystemC 中制作一个模块，但不得不为这个错误而苦恼。

错误:

No instance of constructor "BlackBox::BlackBox with[R=1, expR =3, C=5, expC=-6, T=1, expT=-1]" matches the argument list

不知道哪里出了问题。似乎是这行代码导致的:

dut0 = new BlackBox<1,3, 5,-6, 1,-4> ("DUT0");//错误

谁能帮我解决这个问题？我将不胜感激。

我的代码是:

通过查看您的代码和给出的错误，您似乎缺少采用字符串(或指向 char 的指针)参数的 BlackBox 构造函数:

BlackBox::BlackBox(const char *);  // or similar

或

BlackBox::BlackBox(const std::string& s);  // or similar

您需要定义一个类似于上述构造函数的构造函数。
