First many thanks for your reply.
Could you clarify the two functions of extracting phase? Do you refer to some options inside AC simulation setup? Appreciate that you can give me some clue on that. Thanks.

Its behavior is dependent on the starting point. While the results look different, they are equivalent. If you don't like this behavior, use the other phase function.
