Each library file (including the SPICE parts readable-dump library files)
has values of lambda for each technology. These values are used to make
sure the sizes are correct when a two different libraries are used. Most
people don't bother changing the value of lambda for the schematics
technology, and the SPICE parts libraries don't make use of any layout
technologies, so there is usually not a problem. If the layout lambda
values are changing when you read a SPICE parts library, try adjusting only
those layout lambda values in that library.

Electric reports two "schematics" technologies: analog and
digital. Internally, however, there is only one such technology. Also,
neither is listed in the "Change Units" window because it is not considered
to be a technology with a meaningful value of lambda.

Yes, it was listed in earlier versions, but is no longer listed for the
above reason.
