Double Layer Metal CMOS Circuit Layouts Required.

     I would like to  determine  how  efficient  CAD  design
tools  are at producing dense circuit layouts and need exam-
ples of layout from as many different tools as  possible.  I
would  also  like  to compare the results to hand layout. In
order to do this I require examples  of  automatically  gen-
erated  layout  and any examples of what could be considered
"good" hand layout. The layout should preferably be  in  CIF
format, but almost any format will do as we have a number of
conversion programs.

     Form a security point of view there maybe a  reluctance
to  send layout of whole chips, in which case I'd be just as
happy to receive part of a layout (I'm not interested in the
connections  to  pads or routing).  Also there is no need to
provide detail of the circuit function it is  sufficient  to
say simply ... adder, logic and RAM block etc.

     I also guarantee that the design in whole or part  will
not  be  used  in  any design or fabricated at any time, and
that the design in whole or part will not be transmitted  to
any other person.

     Could you please state whether the layout was  done  by
hand  or  automatically. If automatic layout is sent can you
please say which tool was used.

     Thanks in advance for your help
