Importing LEF of analog block to SOC encounter

[savi]

Hi all,
We have imported the lef file of the analog block into SOC Encounter.
But the analog block does not contain all the pins.
Eg: The lef file of inverter consists of 4 pins namely:
out,in,gnda,vdd
But after importing to SOC the analog block has only out, in, gnda.
vdd pin is not obtained.
But we have got all the 4 corresponding ANALOGESD pads.
The log of this displays as follows:

Loading Lef file ../lefs/inv.lef...
**WARN: (SOCLF-246): The 'UNITS' attribute should be set
in the first lef file (technology lef). There is an attempt to set it
in subsequent lef files which will be ignored.
**WARN: (SOCLF-200): Pin 'gnda' in macro 'inv2' has no
ANTENNADIFFAREA attribute defined.
For any non-power/ground input or inout pin, The attribute should be
defined if any area ratio antenna attribute is defined on any layer.
**WARN: (SOCLF-200): Pin 'gnda' in macro 'inv2' has no
ANTENNAGATEAREA attribute defined.
For any non-power/ground input or inout pin, The attribute should be
defined if any area ratio antenna attribute is defined on any layer.
**WARN: (SOCLF-200): Pin 'out' in macro 'inv2' has no
ANTENNADIFFAREA attribute defined.
For any non-power/ground input or inout pin, The attribute should be
defined if any area ratio antenna attribute is defined on any layer.
**WARN: (SOCLF-200): Pin 'out' in macro 'inv2' has no
ANTENNAGATEAREA attribute defined.
For any non-power/ground input or inout pin, The attribute should be
defined if any area ratio antenna attribute is defined on any layer.
**WARN: (SOCLF-200): Pin 'in' in macro 'inv2' has no
ANTENNADIFFAREA attribute defined.
For any non-power/ground input or inout pin, The attribute should be
defined if any area ratio antenna attribute is defined on any layer.

Hi,
I think you can safely ignore the above warnings and proceed with integration.
