FILL* on schematic unbound LVS error

Anklon

I have imported my .cdl netlist file which contains all the standard cell connection information along with FILL and ENDCAP cells. Normally due to unbound error, I have to run LVS with "abortOnUnboundDevice" nil on. My LVS gives this error:

ERROR    Device 'ENDCAP(Generic)' on schematic is unbound to any Layout device.,

ERROR    Device 'FILL1(Generic)' on schematic is unbound to any Layout device.,

ERROR    Device 'FILL2(Generic)' on schematic is unbound to any Layout device.,

How could I solve this problem? Is there any problem with my filler standard cell library design ? I'm using ASSURA LVS check. 

I can avoid this error by deleting all the filler and endcap information from netlist as they do not have anything to do with schematic of the circuit. They have no physical connection with any block of the circuit. Is it ok ? I would really like a solution without any manual modification of the netlist design.

    Please can you contact customer support - it's going to be hard to answer this without a better idea about what the CDL netlist looks like, what you've imported, and what's in the layout - plus what the LVS rules are doing.

    Regards,

    Andrew.
