In reply to kumar.agnishaman@tevatrontech.com:
I want to understand what do you mean by connecting both the interfaces.
Does it mean your DUT has two interfaces APB and AHB separately? And you want both the interfaces to be driven by your agents.
If its so again you need to map it in TB_TOP which is your top level testbench module.
Apart from that I am unable to understand the connect both interfaces to each other and where. Whatever the mapping you want to do to DUT will be done at testbench module level.
Thanks for explaining your requirements.
