2. Qsys Tutorial

This chapter demonstrates how to use the Avalon-ST Source and Sink BFMs to verify

the functionality of an Avalon-ST component using a Qsys-generated testbench. In

this example, the Avalon-ST Single-Clock FIFO buffer is the DUT. The testbench

includes both the Avalon-ST Source and Sink BFMs to verify the DUT behavior.

Software Requirements

The following software and file are required to run the test:

■ Quartus II software, version 11.0 or later.

■ ModelSim-AE software that you installed with the Quartus II software.

■ The ug_avalon_verification.zip file. This design example file is available for

download at www.altera.com/literature/ug/ug_avalon_verification.zip.

Verifying Avalon-ST DUT

Figure 2–1 shows the test setup to verify the Avalon-ST Single-Clock FIFO buffer

using the Avalon-ST Source and Sink BFMs. The Avalon Clock Source and Reset

Source BFMs provide clock and reset functionalities to the DUT. The Avalon-ST

Source BFM connects to the DUT and drives transactions. The Avalon-ST Sink BFM

monitors transactions from the Avalon-ST Single-Clock FIFO buffer. The test program

controls the BFMs using the BFM API to drive and monitor transactions.
