tb_test.sv—Section 3
Example A–3 shows the third section of the code.
In this code, after reset has gone high, the video source and sink BFM objects are
constructed with the previously declared mailboxes. Then, some method calls are
made to configure the transport mechanism, name the objects (for reporting
purposes), and set some attributes regarding readiness and probability of long delays.
