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 transaction_done field to 1
when the phase completes.

Example

-- Create a slave transaction. Creation returns tr_id to identify
-- the transaction.
create_slave_transaction(tr_id, bfm_index, axi4_tr_if_0(bfm_index));

....

-- Execute the read data phase for the tr_id transaction.
execute_read_data_phase(tr_id, bfm_index, axi4_tr_if_0(bfm_index));
