    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?

  2. 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.
