set_byte_type()
April 2014
set_byte_type()
This nonblocking procedure sets a byte_type field array element for a master transaction that is
uniquely identified by the transaction_id field previously created by the
create_master_transaction() procedure.
The byte_type 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 master transaction containing 3 transfers.
-- Creation returns tr_id to identify the transaction.
create_master_transaction(3, tr_id, bfm_index,
axi4stream_tr_if_0(bfm_index));
-- Set the byte_type field to data for the first byte
-- of the tr_id transaction.
set_byte_type(AXI4STREAM_DATA_BYTE, 0, tr_id, bfm_index,
axi4stream_tr_if_0(bfm_index));
-- Set the byte_type field to null for the second byte
-- of the tr_id transaction.
set_byte_type(AXI4STREAM_NULL_BYTE, 1, tr_id, bfm_index,
axi4stream_tr_if_0(bfm_index));
