get_read_or_write()
April 2014
get_read_or_write()
This nonblocking procedure gets the read_or_write field for a transaction that is uniquely
identified by the transaction_id field previously created by either the
create_write_transaction() or procedure.
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, axi4_tr_if_0(bfm_index));
....
-- Get the read_or_write field of the tr_id transaction.
get_read_or_write(read_or_write, tr_id, bfm_index,
axi4_tr_if_0(bfm_index));
