In reply to chr_sue:
hmm, but the point is to make the TB extensible. If its started on null, he will have to have pointers to all the sequencers in the virtual sequence itself, which is a bad design.
“The develop sequences for your agents sequencer and run them in parallel (fork/join) from a virtual sequence. Then you have completely different data in each agent and on your virtual interfaces” - driving random data blindly may not help, he should implement the behavior of the connecting agents correctly and the vseq should be used to model that.
