rich,
Thanks.
Finally, I got the stream and see it in the waveform.
My suggestion is this, put it into a document or a video somewhere. Because the stream are automatic created, I have no idea where they are and I don’t know blue cross is a stream. Even I know the blue cross are streams,if you didn’t point them to me, I have to go up and down all the structure to find them. And my gut feeling is that they should be in the sequencer (Of course I was wrong, in this case).
Now I understand that why in the forum people suggest to dump all the signals, then find the streams. Which seems ridiculous to me but it does work.
Again, this is a three years feature. If you create a feature, you should make it easy to use instead of hiding it. And, if streams is created, a easier way should be provided to find it.
So, is there general rule to find the automatic created streams ? And, if I do do_record() function on a transaction, where can I find the streams ?
