    Timing Closure on metal filled GDS

    Hi,

    It is said that timing should be checked even on the metal-filled gds since the metal fill can have some effects on the timing of the design. How are these timing checks carried out, in which tool ?

    Can you please elaborate ?

    Thanks,
    Aditya

    In cadence environment (innovus), you are supposed to import a DEF file with the externally-generated fill shapes into the design. timing analysis takes care of the rest.

    How do we import the externally generated fill shapes into the design ? Since the metal fill would be done in Calibre
