In additon, some actions like display of the netlist
browser are suppressed until "final" is true for
"_finish".
TODO: Layout#get_info should never segfault.
The solution is to take intruder instances from as
far as possible in the hierarchy. This provides a
performance improvement in some cases, specifically
if this leads to compression of contexts.
Rerun LVS: a button is provided which allows re-running
the LVS or netlist extraction from the netlist browser.
TODO: a generic concept for triggering the generators
"Partial LVS" is a feature where it's possible to
select a layout subcell - running LVS then will only
compare against the corresponding schematic subcell, not
the whole tree. The magic is done by "align" which will
remove the upper hierarchy part.
Plus: added some missing files
Implementation details:
* scaling factor was introduced in DeviceExtractor::extract
* for easy implementation this is available in "sdbu"
* "sdbu" is made available in GSI
* to test this, the db::compare_netlist had to be enhanced to
exactly check device parameters
* enhancement of LVS script framework and doc updates
1.) tl::Stream now can read from resources
(:<path> URL's)
2.) LVS/DRC templates are kept as resource,
"create_template" uses the URL to read them.
3.) Added samples for LVS
4.) Configured LVS to match sample
- LVS DSL debugging, enhancements
- Allow polygons with holes in L2N
- Spice Reader: was creating too many class objects
- Device class categorizer: allow associating A->C,B-C
- ...
- edge pairs are normalized before turning them into polygons.
This makes flat and deep implementation more consistent.
- deep region and flat regions were not cooperating in geo
checks
- unnamed layers are not registered in make_layer - this
does not make sense and will just hold a fake ref
- tests now use GDS to represent texts after transformation
(with orientation, OASIS can't do this)
- texts are more consistently handled in the tests
- test debug output is not written in the same format
than golden data unless special normalization is
requested.
- a non-orientable polygon was converted to orientable in
a text because this can be represented in GDS consistently
- DRC testsuite uses "polygons" instead of "input" to achieve
identical behavior for deep and flat mode with respect to
texts
- dbRegionTests are updated because texts are not allowed
for non-original layers too
