CLASS

uvm_reg_item

Defines an abstract register transaction item. No bus-specific information is present, although a handle to a uvm_reg_map is provided in case a user wishes to implement a custom address translation algorithm.

Variables

Name	Type	Description
element_kind	uvm_elem_kind_e	Variable element_kind Kind of element being accessed REG, MEM, or FIELD. See uvm_elem_kind_e.
element	uvm_object	Variable element A handle to the RegModel model element associated with this transaction. Use element_kind to determine the type to cast to: uvm_reg, uvm_mem, or uvm_reg_field.
kind	uvm_access_e	Variable kind Kind of access READ or WRITE.
value	uvm_reg_data_t	Variable value The value to write to, or after completion, the value read from the DUT. Burst operations use the values property.
offset	uvm_reg_addr_t	Variable offset For memory accesses, the offset address. For bursts, the starting offset address.
status	uvm_status_e	Variable status The result of the transaction IS_OK, HAS_X, or ERROR. See uvm_status_e.
local_map	uvm_reg_map	Variable local_map The local map used to obtain addresses. Users may customize address-translation using this map. Access to the sequencer and bus adapter can be obtained by getting this map's root map, then calling uvm_reg_map::get_sequencer and uvm_reg_map::get_adapter.
map	uvm_reg_map	Variable map The original map specified for the operation. The actual map used may differ when a test or sequence written at the block level is reused at the system level.
path	uvm_path_e	Variable path The path being used or .
parent	uvm_sequence_base	Variable parent The sequence from which the operation originated.
prior	int	Variable prior The priority requested of this transfer, as defined by uvm_sequence_base::start_item.
extension	uvm_object	Variable extension Handle to optional user data, as conveyed in the call to write(), read(), mirror(), or update() used to trigger the operation.
bd_kind	string	Variable bd_kind If path is UVM_BACKDOOR, this member specifies the abstraction kind for the backdoor access, e.g. "RTL" or "GATES".
fname	string	Variable fname The file name from where this transaction originated, if provided at the call site.
lineno	int	Variable lineno The file name from where this transaction originated, if provided at the call site.
