Subscribers are basically listeners of an analysis port. They subscribe to a broadcaster and receive objects whenever an item is broadcasted via the connected analysis port. A uvm_component class does not have an in-built analysis port, while a uvm_s…

subscriber是消费,用户的意思 uvm_subscriber主要作为coverage的收集方式之一 uvm_subscriber的代码非常简单,继承于uvm_component,再加上一个analysis export而已. 其代码如下: virtual class uvm_subscriber #(type T=int) extends uvm_component; typedef uvm_subscriber #(T) this_type; uvm_analysis_imp #(T,…

1)uvm_component从uvm_report_object继承而来,提供的功能包括: 1)Hierarchy,-----searching and traversing component hierachy 2)Phasing-----调用uvm_phase以及预先定义的很多phase 3)config-------调用config_db的methods 4)report-------调用uvm_report的methods 5)Factory-----调用factory的methods…

UVM中的类包括:基类(base)------------uvm_void/uvm_object/uvm_transaction/uvm_root/uvm_phase/uvm_port_base 报告(reporting)--------uvm_report_object/uvm_report_handler/uvm_report_server/uvm_report_catcher Factory---------uvm_*_register/uvm_factory 配置(config)----…

UVM的文件组织方式很有意思,比如,在src/comps/ 下的所有文件都通过uvm_comps.svh 包含进去. `include "comps/uvm_pair.svh" `include "comps/uvm_policies.svh" `include "comps/uvm_in_order_comparator.svh" `include "comps/uvm_algorithmic_comparator.svh"…
