get_transfer()
This blocking task gets a slave transfer previously created by the create_slave_transaction()
function, and identified by the optional index argument.
It sets the TREADY protocol signal at the appropriate time defined by the transaction
ready_delay field, and sets the transfer_done array index element field to 1 when the transfer is
complete.
If this is the last transfer of the transaction, then it sets the transaction_done field to 1 and
returns the last argument set to 1 to indicate the whole transaction is complete.
Example
// Declare a local variable to hold the transaction record.
axi4stream_transaction trans;
// Create a slave transaction and assign it to the local
// trans variable.
trans = bfm.create_slave_transaction();
....
// Get the first transfer of the trans transaction.
bfm.get_transfer(trans, 0, last);
// Get the second transfer of the trans transaction.
bfm.get_transfer(trans, 1, last);
