CLASS

uvm_push_driver #(REQ,RSP)

Base class for a driver that passively receives transactions, i.e. does not initiate requests transactions. Also known as push mode. Its ports are typically connected to the corresponding ports in a push sequencer as follows:

  push_sequencer.req_port.connect(push_driver.req_export);
  push_driver.rsp_port.connect(push_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
req_export	uvm_blocking_put_imp#(uvm_sequence_item, uvm_push_driver#(uvm_sequence_item, uvm_sequence_item))	Port req_export This export provides the blocking put interface whose default implementation produces an error. Derived drivers must override put with an appropriate implementation (and not call super.put). Ports connected to this export will supply the driver with transactions.
rsp_port	uvm_analysis_port#(uvm_sequence_item)	Port rsp_port This analysis port is used to send response transactions back to the originating sequencer.
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

function void

check_port_connections()

virtual function void

end_of_elaboration_phase(uvm_phase phase)

Parameters:

phase (uvm_phase)

virtual function string

get_type_name()

Tasks

virtual function

put(uvm_sequence_item item)

Parameters:

item (uvm_sequence_item)
