rand uvm_reg_data_t value
Mirrored field value. This value can be sampled in a functional coverage model or constrained when randomized.
Get the simple name
Return the simple object name of this field
virtual function string get_full_name()
Get the hierarchical name
Return the hierarchal name of this field The base of the hierarchical name is the root block.
virtual function int unsigned get_lsb_pos()
Return the position of the field
Returns the index of the least significant bit of the field in the register that instantiates it. An offset of 0 indicates a field that is aligned with the least-significant bit of the register.
virtual function int unsigned get_n_bits()
Returns the width, in number of bits, of the field.
static function int unsigned get_max_size()
Returns the width, in number of bits, of the largest field.
virtual function void set_rand_mode( bit rand_mode )
Modifies the rand_mode for the field instance to the specified one
@uvm-contrib This API is being considered for potential contribution to 1800.2
virtual function bit get_rand_mode()
Returns the rand_mode of the field instance

virtual function string get_access( uvm_reg_map map = null )
Get the access policy of the field
Returns the current access policy of the field when written and read through the specified address map. If the register containing the field is mapped in multiple address map, an address map must be specified. The access policy of a field from a specific address map may be restricted by the register’s access policy in that address map. For example, a RW field may only be writable through one of the address maps and read-only through all of the other maps. If the field access contradicts the map’s access value (field access of WO, and map access value of RO, etc), the method’s return value is NOACCESS.
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
This is an implementation of uvm_reg_field as described in 1800.2 with the addition of API described below.
class uvm_reg_field extends uvm_object
Mirrored field value.
rand uvm_reg_data_t value

Return the position of the field
virtual function int unsigned get_lsb_pos()
Returns the width, in number of bits, of the field.
virtual function int unsigned get_n_bits()

static function int unsigned get_max_size()
Modifies the rand_mode for the field instance to the specified one
virtual function void set_rand_mode( bit rand_mode )
Returns the rand_mode of the field instance
virtual function bit get_rand_mode()
Get the access policy of the field
