// Title: Sequence Item Pull Ports
//
// This section defines the port, export, and imp port classes for
// communicating sequence items between <uvm_sequencer #(REQ,RSP)> and
// <uvm_driver #(REQ,RSP)>.
//-----------------------------------------------------------------------------

//-----------------------------------------------------------------------------
//
// Class: uvm_seq_item_pull_port #(REQ,RSP)
//
// UVM provides a port, export, and imp connector for use in sequencer-driver
// communication. All have standard port connector constructors, except that
// uvm_seq_item_pull_port's default min_size argument is 0; it can be left
// unconnected.
//
//-----------------------------------------------------------------------------

  `UVM_SEQ_ITEM_PULL_IMP(this.m_if, REQ, RSP, t, t)

//-----------------------------------------------------------------------------
//
// Class: uvm_seq_item_pull_export #(REQ,RSP)
//
// This export type is used in sequencer-driver communication. It has the
// standard constructor for exports.
//
//-----------------------------------------------------------------------------

//-----------------------------------------------------------------------------
//
// Class: uvm_seq_item_pull_imp #(REQ,RSP,IMP)
//
// This imp type is used in sequencer-driver communication. It has the
// standard constructor for imp-type ports.
