Examples for BFM tester

Presented in this repository are several examples based on BFM tester, a highly-flexible way to write tests for Chisel HDL.

Example 1: AXI-Stream and AXI4-Lite

As a "Hello World"-style example, a module with 2 AXI-Stream input ports, 2 AXI-Stream output ports and an AXI4-Lite control port is instantiated and tested.

Example 2: XGMII statistics module

BfmTester also allows the integration of custom (i.e. provided by the user of the tester) bus functional models. This example provides driver and monitor for a 10 gigabit media-independent interface (XGMII).

Example 3: Feedthrough

This example connects directly AXI-Stream Master to an AXI-Stream Slave with direction connection.

This example is not working correctly - the same test passes and fails for different seeds. The purpose of this example is to demonstrate the current limitation of the BFM tester.

Example 4: Generated AXI4-Lite subordinate

This example uses AxiLiteSubordinateGenerator to generate a module with an AXI4-Lite interface which provides a control and status access to the internal logic.
