我正在尝试使用 Linux 中的 SV 验证环境来运行我的计数器，因为我创建了不同的文件，并且我正在尝试通过包访问这些文件，但即使我导入包，我的测试文件也没有在我的顶级文件中运行.

我试图通过创建 Makefile 来运行我的计数器，但它向我显示以下错误
error 1 : my_test is of unknown type or did you omit '()' for an instantiation
error 2 : test_h is not a variable
error 3 : Illeagal LHS of assignment
error 4 : new must be used to assign for a class or covergroup handle
您正在将类型为 count_if 的 alleged 接口分配给 3 个不兼容的类型：
您不想在包中包含“test.sv”。如果你这样做了，那么在其中导入 count_pkg 就没有意义了。
我建议将您的代码发布到 EDA Playrground。
没有行号的错误消息不是最有帮助的。
