7.8.2. Avalon-ST Interface (Output FIFO Buffer) with Backpressure

This example demonstrates the Avalon-ST input interface and the Avalon-ST output interface blocks. This example has FIFO buffers in the output interface only. Use manual switches in the testbench to change when downstream is ready for data or to turn off input. The simulation ends by turning off incoming data and ensures that it writes out as many valid data cycles as it receives.

The model file is demo_avalon_st.mdl.
