I want to read-in a previously generated design to
test out the area/maze routing features in electric.
I have both the full LEF (with technology, sites, macros,
rules etc...) as well as the corresponding DEF with
components, nets and special nets sections.
My question is - what exactly is the currently level of
LEF/DEF support in the tool? I want to create a library
including the basic cells (this works); then create a
schematic facet and import the DEF to provide the instantiation
and connectivity info (this did not work for me). Finally,
I want to use the router to connect-up the ports (DEF has all
required placement and connectivity data).
As this did not work as I expected, what am I missing?
Any guidance or feedback is appreciated.
Thanks,
---Andrew
ps. Also, am I correct in assuming that the OBS keyword in LEF
and non-DEFAULT via rules are NOT currently supported?
