5.2. Block Diagram

The following figure provides a block diagram of the Avalon-MM Master BFM. As this figure illustrates, the BFM includes the following major blocks:
  • Avalon-MM Master API—Provides methods to create Avalon-MM transactions and query the state of all queues.
  • Command Descriptor—Accumulates the fields of an Avalon-MM command transaction using the set_command API call. Inserts completed commands onto the pending command queue.
  • Avalon-MM Interface Driver—Issues transfers to the system interconnect fabric and holds each transfer until waitrequest is deasserted. For burst transfers, there is a separate transfer for each word of the burst. The system interconnect fabric can assert waitrequest for each word of the burst, as necessary.
  • Timestamp Counter—Records a timestamp with commands for use in timing calculations. The driver and monitor both use the timestamp counter for timing calculations.
  • Avalon-MM Interface Monitor—Monitors the system interconnect fabric and records responses for read transfers in the response queue.
  • Response Descriptor—Collects information about completed transactions using the get_response_<rolename> API calls. The testbench uses this information for further analysis.
  • Public Events—Provides status response that arrives together with the data. The public event signals indicate the status of the Master’s request, such as successful completion, timeout, or error.
