Hi all,



I need to generate svdb database in LVS/PEX process.

LVS passed and got a smile, but svdb database is never generated well



The error message is:

"
Error 179: Error reading file "svdb/ltx_m200_clk_inv16x.phdb/db/master/layers.toc": No such file or directory.

"



and here are three warnings I got:

"

Warning: #1 in ltx_m200_clk_inv16x
WARNING: Cannot enable LVS PUSH DEVICES because pin location information was requested.

Warning: #2 in ltx_m200_clk_inv16x
WARNING: Invalid PATHCHK request "! POWER": no POWER nets present, operation aborted.

Warning: #3 in ltx_m200_clk_inv16x
WARNING: Invalid PATHCHK request "! GROUND": no GROUND nets present, operation aborted

"



I've faced this issue for two weeks. Please help me and please ask any information you want.



Calibre version: 2017.1_25 & 2017.3_29
