execute_read_data_phase()

This procedure executes a read data phase that is uniquely identified by the transaction_id
argument previously created by the

create_slave_transaction()

procedure. This phase can be

blocking (default) or nonblocking, defined by the transaction record operation_mode field.

The execute_read_data_phase() sets the RVALID protocol signal at the appropriate time
defined by the transaction record data_valid_delay field and sets the data_beat_done array
index element field to 1 when the phase completes. If this is the last data phase (beat) of the
burst, it also sets the transaction_done field on completion.
