pure virtual function void order( ref uvm_reg_bus_op q[$] )
the order() function may reorder the sequence of bus transactions produced by a single uvm_reg transaction (read/write). This can be used in scenarios when the register width differs from the bus width and one register access results in a series of bus transactions. the first item (0) of the queue will be the first bus transaction (the last($) will be the final transaction
Address map abstraction class
This class represents an address map. An address map is a collection of registers and memories accessible via a specific physical interface. Address maps can be composed into higher-level address maps.
Address maps are created using the uvm_reg_block::create_map() method.

virtual function void set_sequencer ( uvm_sequencer_base sequencer, uvm_reg_adapter adapter = null )
Set the sequencer and adapter associated with this map. This method must be called before starting any sequences based on uvm_reg_sequence.
virtual function void set_submap_offset ( uvm_reg_map submap, uvm_reg_addr_t offset )
Set the offset of the given submap to offset.
virtual function uvm_reg_addr_t get_submap_offset ( uvm_reg_map submap )
Return the offset of the given submap.
virtual function void set_base_addr ( uvm_reg_addr_t offset )
Set the base address of this map.
Get the simple name
Return the simple object name of this address map.
virtual function string get_full_name()
Get the hierarchical name
Return the hierarchal name of this address map. The base of the hierarchical name is the root block.
virtual function int unsigned get_n_bytes ( uvm_hier_e hier = UVM_HIER )
Get the width in bytes of the bus associated with this map. If hier is UVM_HIER, then gets the effective bus width relative to the system level. The effective bus width is the narrowest bus width from this map to the top-level root map. Each bus access will be limited to this bus width.
virtual function int unsigned get_addr_unit_bytes()
Get the number of bytes in the smallest addressable unit in the map. Returns 1 if the address map was configured using byte-level addressing. Returns get_n_bytes() otherwise.
function bit get_check_on_read()
Gets the check-on-read mode setting for this map.
virtual task do_bus_write ( uvm_reg_item rw, uvm_sequencer_base sequencer, uvm_reg_adapter adapter )
Perform a bus write operation.
virtual task do_bus_read ( uvm_reg_item rw, uvm_sequencer_base sequencer, uvm_reg_adapter adapter )
Perform a bus read operation.
ie. every memory location will get an own bus address (and bits on the bus larger than the memory width are discarded otherwise the memory access is ‘packed’
same as get_physical_addresses() but stops at the specified map
The uvm_void class is the base class for all UVM classes.
virtual class uvm_void
The uvm_object class is the base class for all UVM data and hierarchical classes.
virtual class uvm_object extends uvm_void
virtual class uvm_reg_transaction_order_policy extends uvm_object
class uvm_reg_map extends uvm_object
