我试图在SystemC中创建一个模块但是必须努力解决这个错误。
错误：
没有构造函数的实例＆＃34; BlackBox :: BlackBox [R = 1，expR = 3，C = 5，expC = -6，T = 1，expT = -1]＆＃34;匹配参数列表
我不知道问题出在哪里。 似乎这行代码导致了它：
dut0 = new BlackBox<1,3, 5,-6, 1,-4> ("DUT0"); //错误
有人可以帮我解决这个问题吗？我会非常感激。
我的代码是：

答案 0 :(得分：0)
通过查看代码和给出的错误，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。
