CLASS

uvm_driver #(REQ,RSP)

The base class for drivers that initiate requests for new transactions via a uvm_seq_item_pull_port. The ports are typically connected to the exports of an appropriate sequencer component.

This driver operates in pull mode. Its ports are typically connected to the corresponding exports in a pull sequencer as follows:

    driver.seq_item_port.connect(sequencer.seq_item_export);
    driver.rsp_port.connect(sequencer.rsp_export);

The rsp_port needs connecting only if the driver will use it to write responses to the analysis export in the sequencer.

Parameters

Name	Default value	Description
REQ	uvm_sequence_item
RSP	REQ

Variables

Name	Type	Description
seq_item_port	uvm_seq_item_pull_port#(uvm_sequence_item, uvm_sequence_item)	Port seq_item_port Derived driver classes should use this port to request items from the sequencer. They may also use it to send responses back.
seq_item_prod_if	uvm_seq_item_pull_port#(uvm_sequence_item, uvm_sequence_item)	alias
rsp_port	uvm_analysis_port#(uvm_sequence_item)	Port rsp_port This port provides an alternate way of sending responses back to the originating sequencer. Which port to use depends on which export the sequencer provides for connection.
req	uvm_sequence_item
rsp	uvm_sequence_item
type_name	string

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 string

get_type_name()
