get_transfer()

April 2014

get_transfer()

This blocking task gets a monitor transfer previously created by the

create_monitor_transaction() function and identified by the optional index argument.

It sets the transfer_done array index element field to 1 when the transfer completes.

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 monitor transaction and assign it to the local

// trans variable.

trans = bfm.create_monitor_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);
