In reply to harshbandil:
I’d like to underline what cgales is saying. You are running into big trouble if you deal with pinlevel signals in the sequence, because it has a completely different synchronisation mechanism
Do you have a pipelined processing of sequences, i.e. a second sequence can be processed before the first on has been completed. Thi is the most simple case. You could haave even more sequences in your pipeline.
