In reply to srikanthvvs1:
I think not necessary. Adapter is used by RAL to convert write/read calls to specific sequence item and execute that on the registered sequencer. This is one method to do it.
ral_model.apb_map.set_sequencer(apb_vip.apb_seqr, apb_reg_adapter);
What’s the second argument to set_sequencer ? Isn’t that the adapter ?
Regarding the User-defined Frontdoor I am not aware on it’s internal working so won’t be able to comment on it .
Just a general idea. Should see if it really works.
Do update us once you have a complete working code .
