Hi Lily,
if you talk about metal density checks, I would suggest using a DRC tool (Dracula, Diva, Assura, Calibre). It may take some more of your time because you have to switch tools (I don't think you can run Assura directly from SE). I think there also is an antenna verification in SE which sometimes gives strange results. I wonder if the implementation of these tools has been improved in SoC-Encounter.
In most cases, the foundry mask shop people take care of adding dummy metal to comply with the density rules. Maybe you don't need to care too much about this (especially in the case of a standard-cell design in SE).
