1.采用uvm_create & uvm_send宏 注1:`uvm_create与`uvm_send宏的第一个参数都可以是sequencer的指针,也可以是transaction的指针; (1)uvm_create/uvm_create_on调用uvm_sequence_base的create_item函数,并利用factory机制进行seq或seq_item的例化; (2)uvm_rand_send系列宏与uvm_send宏的区别在于前者包含了trans...
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 cannot be called on a uvm_component. Use create_component instead.") return null; endfunction 继续深究,为什么uvm_componet不可以通过create()也就是直接new()来创建呢?个人的理解是这样: 第一是因为每个componet都是UVM梳妆环境中的一环,都是有parent和childs的(至少有其一)。所以componet new的时候...
// depends on there being a single proxy instance for each registered type. static function this_type get(); if (me == null) begin uvm_factory f = uvm_factory::get(); me = new; f.register(me); end return me; endfunction
当然X::type_id::create本质依然是调用new()去创建实例,但是问题在于其UVM内部是如何一步步实现调用new()成功创建实例的。 X::type_id从何而来 要实现通过X::type_id::create创建实例,首先需要对需要创建的class X进行factory注册,即使用宏uvm_component_utils(X)(或者uvm_object_utils(X)),从宏uvm_component...

*Project: Base Agent *Description: cfs_agt is a SystemVerilog generic agent, implemented based on UVM methodology. This agent can be easily extended to create very fast an UVM based agent for any protocol. The minimum required effort is to: - declare the interface and a virtual interface typ...
