Indirect data access abstraction class
Models the behavior of a register used to indirectly access a register array, indexed by a second address register.
This class should not be instantiated directly. A type-specific class extension should be used to provide a factory-enabled constructor and specify the n_bits and coverage models.

function new( string name = "uvm_reg_indirect", int unsigned n_bits, int has_cover )
Create an instance of this class
Should not be called directly, other than via super.new(). The value of n_bits must match the number of bits in the indirect register array.
function void configure ( uvm_reg idx, uvm_reg reg_a[], uvm_reg_block blk_parent, uvm_reg_file regfile_parent = null )
Configure the indirect data register.
The idx register specifies the index, in the reg_a register array, of the register to access. The idx must be written to first. A read or write operation to this register will subsequently read or write the indexed register in the register array.
The number of bits in each register in the register array must be equal to n_bits of this register.
See uvm_reg::configure() for the remaining arguments.
The uvm_object class is the base class for all UVM data and hierarchical classes.
