Need help on agent architecture

[santhosh2020]

I have DUT interface  with A,B (list of singals) that needs to be driven with some timing dependency . A is cmd interface ,B is data interface .  Now i plan to implement driver should i have separate sequence  from signals list A and signals list B . If so how would i synchronize two sequences sequences so that i meet the timing relation between these two  . Or should i have implemeted both cmd and data in same sequence item and have the logic in driver so it driver cmd and data after timing is meet . I dont like this approach as i need fill my driver with timing code . I want my timing information to be in sequence .

You do not say anything about a relationship between interface A and B, i.e. can you do a few transactions on the cmd interface without needing the data from the data interface or vice versa. Please elaborate.
