That’s exactly the problem. You can’t run h_seq* parameterized by h_pkt on a sequencer that is expecting lower_pkt. The issue is that this is no longer a standard layering. h_seq1 and h_seq3 should be parameterized with lpkt1 and h_seq2 and h_seq4 should be parameterized with lpkt2. You’ll need to make sure that these sequences call the lower_sequences rather than expecting the lower_sequences to call get().
