get_data_valid_delay()
This nonblocking procedure sets the data_valid_delay field for a transaction that is uniquely
identified by the transaction_id field previously created by the
create_slave_transaction()
procedure.
Example
-- Create a slave transaction with start address of 0.
-- Creation returns tr_id to identify the transaction.
create_slave_transaction(tr_id, bfm_index, axi4_tr_if_0(bfm_index));
....
-- Get the write channel WVALID delay for the data
-- phase (beat) of the tr_id transaction.
get_data_valid_delay(data_valid_delay, tr_id, bfm_index,
axi4_tr_if_0(bfm_index));
