Electric can read both EDIF schematics and layout.  However Electric 
supports only simple EDIF (version 2 0 0).

When reading layout, the circuit appears as unconnected pieces of 
geometry instead of connected transistors and contacts.  Some of 
Electric's tools won't care (such as GDS output, which will be 
correct).  Other tools will not work well, such as NCC (Electric's 
LVS).  Even the design-rule checker makes use of connectivity and 
will have problems.  You can try running Electric's node extractor, 
but that doesn't always work, and you may have to hand-edit the 
circuit to make full use of Electric.

When reading schematics, you should have a correctly constructed set 
of schematics which have been laid-out on a regular grid.  You can 
simulate them and LVS them.
