execute_read_addr_phase()

This procedure executes a master read address phase uniquely identified by the transaction_id
argument previously created by the

create_read_transaction()

procedure. This phase can be

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

It sets the ARVALID protocol signal at the appropriate time defined by the transaction record
address_valid_delay field.

AXI3 Example

-- Create a read transaction with start address of 0.
-- Creation returns tr_id to identify the transaction.
create_read_transaction(0, tr_id, bfm_index, axi_tr_if_0(bfm_index));

-- Set the ID to 1 for this transaction
set_id(1, tr_id, bfm_index, axi_tr_if_0(bfm_index));

-- Execute the read address phase for the tr_id transaction.
execute_read_addr_phase(tr_id, bfm_index, axi_tr_if_0(bfm_index));
