Class providing the non-blocking backward transport port.

class uvm_tlm_req_rsp_channel #( type  REQ  =  int, type  RSP  =  REQ ) extends uvm_component

The uvm_tlm_req_rsp_channel contains a request FIFO of type REQ and a response FIFO of type RSP.

Canonical time type that can be used in different timescales

class uvm_tlm_transport_channel #(     type  REQ  =  int,     type  RSP  =  REQ ) extends uvm_tlm_req_rsp_channel #(REQ, RSP)

A uvm_tlm_transport_channel is a uvm_tlm_req_rsp_channel #(REQ,RSP) that implements the transport interface.

class uvm_top_down_visitor_adapter#(     type  STRUCTURE  =  uvm_component,       VISITOR  =  uvm_visitor#(STRUCTURE) ) extends uvm_visitor_adapter#(STRUCTURE,VISITOR)

This uvm_top_down_visitor_adapter traverses the STRUCTURE s (and will invoke the visitor) in a hierarchical fashion.

virtual class uvm_topdown_phase extends uvm_phase

Virtual base class for function phases that operate top-down.

virtual class uvm_tr_database extends uvm_object

The uvm_tr_database class is intended to hide the underlying database implementation from the end user, as these details are often vendor or tool-specific.

virtual class uvm_transaction extends uvm_object

The uvm_transaction class is the root base class for UVM transactions.

class uvm_tree_printer extends uvm_printer

By overriding various methods of the uvm_printer super class, the tree printer prints output in a tree format.

The uvm_visitor class provides an abstract base class for a visitor.

The visitor adaptor traverses all nodes of the STRUCTURE and will invoke visitor.visit() on every node.

virtual class uvm_void

The uvm_void class is the base class for all UVM classes.

class uvm_vreg extends uvm_object

Virtual register abstraction base class

virtual class uvm_vreg_cbs extends uvm_callback

Pre/post read/write callback facade class

class uvm_vreg_field extends uvm_object

Virtual field abstraction class

virtual class uvm_vreg_field_cbs extends uvm_callback

Pre/post read/write callback facade class
