UVM에서 제공하는 단순한 uvm_in_order_class_comparator 를 사용하여 간단하게. In essense, the uvm_subscriber class is a component with a built-in analysis export. For convenience, UVM pre-defines three print policies (uvm_default_table_printer, uvm_default_tree_printer, and uvm_default_line_printer; lines 5 to 7). 2 Design of Interconnect Block. The UVM monitor functionality should be limited to basic monitoring that is. uvm_subscriber #( type T = int ) extends uvm_component This class provides an analysis export for receiving transactions from a connected analysis export. The uvm_subscriber base component can be used to simplify this operation, so a typical analysis component would extend uvm_subscriber as: class sub1 #(type T = simple_trans) extends uvm_subscriber #(T);. The paper explains how UVM can be integrated with SystemC using the UVM-ML Open Architecture, a framework that enables interoperability between different. tpl. UVMを使用したクラスファイル群は「Verilog Header」として表. Description `uvm_register_cb(T, CB) Registers the user-defined callback which is extended from uvm_callback. It provides a way to publish resources by a certain class, without the consumers of these resources to have to know anything about the publisher besides the key by which to pull the resource. The run_test() method call to construct the UVM environment root component and then initiates the UVM phasing mechanism. The generated subscriber component would now look like this, leaving you to define the actual content of the class in the include files: class clkndata_coverage extends uvm_subscriber #(data_tx); `uvm_component(clkndata_coverage) `include "clkndata_cover_inc_inside. . uvm_env is extended from uvm_component and does not contain any extra functionality.
