CLASS

uvm_subscriber

This class provides an analysis export for receiving transactions from a connected analysis export. Making such a connection "subscribes" this component to any transactions emitted by the connected analysis port.

Subtypes of this class must define the write method to process the incoming transactions. This class is particularly useful when designing a coverage collector that attaches to a monitor.

Parameters

Name	Default value	Description
T	int

Variables

Name	Type	Description
analysis_export	uvm_analysis_imp#(int, uvm_subscriber#(int))	Port analysis_export This export provides access to the write method, which derived subscribers must implement.

Constructors

function

new(string name, uvm_component parent)

Function

new

Creates and initializes an instance of this class using the normal constructor arguments for uvm_component: name is the name of the instance, and parent is the handle to the hierarchical parent, if any.

Parameters:

• name (string)

• parent (uvm_component)

Functions

virtual function void

write(int t)

Function

write

A pure virtual method that must be defined in each subclass. Access to this method by outside components should be done via the analysis_export.

Parameters:

t (int)
