get_write_data_phase()

This blocking task gets a write data phase previously created by the

create_monitor_transaction() function.The get_write_data_phase() sets the data_beat_done

array index element field to 1 when the phase completes. If this is the last phase (beat) of the

burst, then it returns the transaction last argument set to 1 to indicate the whole burst is

complete.

AXI3 Example

// Declare a local variable to hold the transaction record.

axi_transaction write_trans;

// Create a monitor transaction and assign it to the local

// write_trans variable.

write_trans = bfm.create_monitor_transaction();

....

// Get the write data phase for the first beat of the

// write_trans transaction.

bfm.get_write_data_phase(write_trans, 0, last);

// Get the write data phase for the second beat of the

// write_trans transaction.

bfm.get_write_data_phase(write_trans, 1, last);
