In reply to chr_sue:
Thanks for the suggestion. If I understand correctly, a top level virtual sequence would generate user_data and demultiplex that data into 4 virtual interfaces. And the 4 re-use sequences would access their respective virtual interface (which is declared in their respective sequencer) to grab the demultiplexed data?
I was looking at virtual interface earlier but there are people saying that a sequence shouldn’t have access to virtual interface. Any reason for concerns?
