Could anyone tell me which type of error this information is and how to
deal with?

 

I think the error may have been earlier in the file? The fundamental problem is
that dfIIToVldb failed - nvn won't be able to proceed unless that works.

Unfortunately it's hard to know what the failure is - it could be many genuine
things - and normally it tells you any errors during the dfIIToVldb (the error
message should probably say "dfIIToVldb failed to complete")

right,the error lies in the header of error log files,perhapys the only
way is to recombine layout block and do lvs for each block
firstly.Anymore,thanks Andrew.

I don't understand what you're saying or asking here - is this a question?

Hi Andrew:
My english is not very well. The problem i posted was solved,the
reason is that i did not do check and save of schematic for netlist
renew.After checking and saving schematic,assura work well.Thank you
for your attention.
The another question about Libgen i post was there,it would be very
helpful if you can reply.
