[BDTYP] Cannot create a component of type ‘noc_main_spi_debug_test‘ because it is not registered wi 相当于我们的***.test.sv文件没有被包含到uvm环境中去。 导致浪费了一天的时间在编译和代码排查上。 教训:遇到问题一定不要急忙调试,要首先排查上下游或者上下文的关系,这样才能快速有效解决问题。.....
这允许使用默认值在工厂内构建一个工厂注册类,然后可以将类属性重新赋值给通过uvm_component_registry wrapper类的create方法传递的参数。组件和对象的默认值是不同的: // For a component: class my_component extends uvm_component; function new(string name = "my_component", uvm_component parent = null); ...

create()方法有两个参数,一个是名称字符串,另一个是指向父uvm_component类对象的指针。这些参数的值用于在链表中创建一个条目,UVM使用该条目在伪层次结构中定位uvm_component。此列表用于消息传递和配置机制。按照约定,name参数字符串应该与组件的声明句柄相同,parent参数应该是关键字“this”,以便它引用创建它的uvm_...

uvm_component和uvm_object构造函数是带有原型模板的虚方法,用户必须遵守。为了在构建阶段支持延迟构造,工厂构造函数应该包含构造函数参数的默认值。这允许使用默认值在工厂内构建一个工厂注册类,然后可以将类属性重新赋值给通过uvm_component_registry wrapper类的create方法传递的参数。组件和对象的默认值是不同的: ...
