In reply to A_123:
I understood you r code as follows:
You have 1 master agent and 1 slave agent.
Each agent has a sequencer/driver pair.
The sequencers produces seq_items of the same time. They are parameterized for the same seq_item.
But the drivers differ. Correct?
You can use the seq_item for both sequencers/sequences.
The sequencer is the same. But you might need different sequences for the master and the slave.
This approach is fine.
