ANTENNADIFFAREA value [LAYER layerName]
Specifies the diffusion (diode) area, in micron-squared units, to which the pin is connected on a layer.
If you do not specify a layer name, the value applies to all layers.
The above attribute has to be there in our standard cell lef file, when you are loading the design in IC Compiler.
If it is existed, but not mentioned the layerName then tool will applies to all layers and all the pins.
Here I am giving one example, how it has to be in standard cell lef file have the statements.
PIN Z
DIRECTION OUTPUT ;
USE SIGNAL ;
ANTENNADIFFAREA 0.0225 LAYER M2 ;
PORT
LAYER M2 ;
POLYGON 0.48 0.725 0.075 0.725 0.075 0.675 0.43 0.675 0.43 0.175 0.48 0.175 ;
END
END Z
does my comments helpful to you?
Thanks
