In reply to nani:
If your DUT is the AHB2APB bridge, is it the case that it has an AHB interface on one side and an APB interface on the other? If that’s the case, then your environment would have an AHB agent connected to the AHB interface of your DUT and an APB agent connected to the APB interface. Then, in your environment you could pass any information between the two agents you think you need to.
Does that help?
