Abstract Generator in Cadence

Guest
Hi,

I am trying to create abstracts from the standard cells that I have
made. When I run abstract from the terminal and then try to load my
library that I want to create my abstracts for i get errors.

The errors I get are:

I have tried looking up the errors in the documentation and it seems
that I have to modify the tech library. Is this true?

Yes. The first warnings are probably because somebody has defined various vias
in the tech file, but then these have been deleted from the library. According
to the tech file they're there, but they aren't any more.

The other points are validating various points of the technology rules - and
pointing out inconsistencies. You'll need to fix these, as effectively this
means there is problems with the Technology LEF (if you were to LEF out
the technology library).

Regards,

Andrew.
