Assura : how to copy properties from schematic to layout

[ltao03]

Hi, Assura experts,

With Assura LVS I can extract a netlist from layout, then
I need to compare the netlist, including device properties,
against schematic. Question is, there are some properties
I cannot extract directly from layout, is there any way that I
can copy these properties from schematci to the extracted
netlist?

Thanks,
Liang

I am not farmiler with Assura, but i believe if u didnt define the
property in ur LVS rule file, the extracted netlist wont have it at
all...

the properties u c on the netlist , Not all of them were defined in rule
files, possible be like this ..

Sorry I fail to follow.

The extracted netlist is creates by the extraction deck and the polygons in
the layout.
Any properties in the layout are lost!

What you need to have is an extraction methodology the creates the required
properties from the layout.
This can only be done by clever writing of the extract deck ( and typically
requires you to own the PDK! )
possible but tricky ...
