set_data_valid_delay()
April 2014
set_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_write_transaction()
procedure.
Example
-- Create a write transaction with start address of 0.
-- Creation returns tr_id to identify the transaction.
create_write_transaction(0, tr_id, bfm_index, axi4_tr_if_0(bfm_index));
-- Set the write channel WVALID delay to 3 ACLK cycles for the data
-- phase of the tr_id transaction.
set_data_valid_delay(3, tr_id, bfm_index, axi4_tr_if_0(bfm_index));
