GAFillerCells site

Tetram

Hi all,

I red in a Cadence application note from November 2014, that "GACells is GACORE site based filler insertion while GAFillerCells is CORE site based filler insertion".

However, in my LEF file it is written:

MACRO GFILL
    CLASS CORE ;
    SITE gacore7T ;

And when I try the command
ecoPlace -useGAFillerCells {GFILL}
it is written
**ERROR: (ENCSP-2707):    TechSite 'gacore7T' used by the GAFiller list does not have rows in the design.


Maybe, the easiest way to overcome that is to change the LEF file in
SITE core7T ;

but I'm wondering, will it still work during the ECO flow ?
Will SoC put GA Cells at the place of GA fillers which have a SITE core ?

Thanks a lot !

  • Hi Sebastien,

    Based on my experience handling GA fillers.  The GA fillers should have the same name as your standard cells' SITE name, same goes for the standard cell library of the GA Cells' site.  What you are suggesting is possible, but make sure that gacore7T has the same properties as core7T.
