How seq_item_port/export (Driver/Sequencer) are different from analysis ports?

In reply to mamta_r:

No. The seq_item_port is used exclusively for the sequencer/driver. The methods contained within the seq_item_port are usable only by sequences and not meant for any other use.

What are your trying to accomplish? You have asked the same question several times but haven’t described what you are trying to do.
