In reply to Chandrashekhar Goudar:
You are dealing with Mixed-language designs/sims - an area that’s ill-defined in “standards” and sometimes tool dependent. Having said that - what you are looking for sounds reasonable. I believe tools have ways to do “black-boxing” like what you are looking for. Talk to your vendor (I guess SNPS?).
On the “bind” front - you should be binding to the RTL outputs and not the interconnect inputs (I am assuming CPU-RTL-output → interconnect-input connection). That way you should be able to attach an external driver via bind.
