Error: DC-Topographical Failed to link physical library. (OPT-1428)

Hi,
I am getting this error when i try to run compile_ultra in topographic mode:
Error: DC-Topographical Failed to link physical library. (OPT-1428)

when running not in topo mode everything works.
what should i check?
Thanks!

Did you set the following commands first before optimization ?

set_tlu_plus_files
set_mw_lib_reference
open_mw_lib

This is like set_target_library and you need to specify where the physical library is.

Hi,
No, i did not.
Should i define them only working in topo mode?
Can't i run topo mode without creating mw library?

HI, eeStud,

You have to know that you need extra physical library for topographical mode.
This physical library includes milkyway library and floorplanning information defined by IC compiler.
In the other words, you can't directly apply topographical mode without assistance of back-end info.
This is what I have known, maybe there is some wrong.
