    metal fill on the core circuit

    My chip is low frequency operation under 1MHz clock. For the layout, if the automatically metal fills on my core chip, whether it would influence the chip performance?

    Usually I select the option that the automatically metal fill does not fill onto my core chip, but this time I have to do it, because the current metal density requires. Thank you.

    I doubt metal fills will bother anything below 1GHz.

    I have seen weird things with metal fill, especially in analog. Just make sure to analyze the timing of your digital circuits post-fill, and for the analog either protect the sensitive region against fill or do it somewhat by hand (and perform post layout sim)
