get_byte_type()
This nonblocking procedure gets a byte_type field array element for a monitor transaction that is
uniquely identified by the transaction_id field previously created by the
create_monitor_transaction() procedure.
The byte_type array element is identified by the optional index argument. If no index is
supplied, then the first byte_type is accessed in the array.
Example
-- Create a monitor transaction.
-- Creation returns tr_id to identify the transaction.
create_monitor_transaction(tr_id, bfm_index,
axi4stream_tr_if_0(bfm_index));
-- Get the byte_type field for the first byte of the tr_id transaction.
get_byte_type(byte_type, 0, tr_id, bfm_index,
axi4stream_tr_if_0(bfm_index));
-- Get the byte_type field for the second byte of the tr_id transaction.
get_byte_type(byte_type, 1, tr_id, bfm_index,
axi4stream_tr_if_0(bfm_index));
