set_delay_mode()

This AXI3 nonblocking procedure sets the delay_mode field for a transaction that is uniquely
identified by the transaction_id field previously created by either the

create_write_transaction()

create_read_transaction()

procedure.

AXI3 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, axi_tr_if_0(bfm_index));

-- Set the delay mode of the *VALID to *READY handshake for the
-- tr_id transaction.
set_delay_mode(AXI_VALID2READY, tr_id, bfm_index,
axi_tr_if_0(bfm_index));

AXI4 BFM

Note

This procedure is not supported in the AXI4 BFM API.
