Could you explain how to differentiate the usage between the dreq_o.ready signal for the core and the fetch_obi_rsp_o.gnt signal..?

Yes, sure:

  • dreq_o.req && dreq_o.ready grant the virtual address to decode the cache index. (outside obi protocol)
  • fetch_obi_rsp_o.gnt grants the physical address (after the MMU), --> end of OBI address phase.

Hope this answers your question!
