get_size()

This nonblocking procedure gets the burst size 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 read transaction with start address of 1.
-- Creation returns tr_id to identify the transaction.
create_read_transaction(1, tr_id, bfm_index, axi_tr_if_0(bfm_index));

....

-- Get the burst size of the tr_id transaction.
get_size (size, tr_id, bfm_index, axi_tr_if_0(bfm_index));

Prototype

-- * = axi| axi4
-- ** = AXI | AXI4
