new是OOP自带属性,create是UVM override属性,可以理解成create比new更进阶~ create是用factory模式来construct对象,在factory中注册过的uvm_object扩展类或是uvm_component 扩展类都可以用create,这样做的好处是在testcase里面可以override. new是什么时候都可以用的。 只有与UVM基本类相关的类才可以使用create方法,相当于...

create是用factory模式来construct对象,在factory中注册过的uvm_object扩展类或是uvm_component 扩展类都可以用create,这样做的好处是在testcase里面可以override. new是什么时候都可以用的。 只有与UVM基本类相关的类才可以使用create方法,相当于在UVM这个大树上面挂了个号,具体号码就是通过static function type_id来分配...

()中或build_phase()中都可以,因为并不涉及时间上的先后顺序;但是如果使用type_id::create()创建,则必须要写在高层次的build_phase()中,这可以看作是对UVM特性的延续:如果在高层次的new()中使用type_id::create()创建低层次的对象,因为type_id::create()方式涉及类的覆盖,则可能未覆盖就创建,有覆盖失败的...
1：new()是systemverilog中的类构造函数。2：type_id::create是UVM中特有的方法。两者都是为了创造对象...
In reply totaufeeq_khan: uvm_components are used to create a UVM testbench. This testsbench has different levels of hierachy and has to be maintained. For this reason we need the parent/child relationship. This is supported by the 2nd argument. ...
