get_write_data_phase()

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

Note

For AXI3, the get_write_data_phase() also sets the WREADY protocol signal at the

appropriate time, defined by the transaction record data_ready_delay field.
