Matthias Koefferlein 7d5f61db59 Issue #2360: Implemented name sorting by default (can be turned off) for 'make_top_level_pins' 2026-05-26 23:26:16 +02:00
Matthias Koefferlein 37977d21e9 Fixing issue #2350 (strm2oas writes empty OAS) 
Problem was that the OASIS writer was simply ignoring
all top level proxy cells (PCells, Library references).

The original bug #1835 fixed that by changing the
reader behavior, so it would keep top level proxies.
However, doing the spin through the writer got them
removed and in addition, the cleanup happing during
editing would also remove them.

Solution is to centralize the strategy of cleaning
cells. The cleanup now is changed to not remove
proxy top cells if they are the only ones. This is
consistent with the previous reader-only behavior.

The writer implements the same behavior by means
dropping cells marked for cleanup, instead of simply
skipping all proxy cells.

Matthias Koefferlein c85be6bce5 Adding string serialization "from_s" for objects with properties (CAUTION: side effect!) 
Problem was that "to_s" did not deliver a parsable string for the
properties. This is fixed, but the format of the properties part
of the string changes.

Matthias Koefferlein 7cec679d39 Taking care of complex library reference scenarios where libraries self-reference and under the presence of stale references. Main issue is order of resolution and indirect references due to replication. Solution is to repeat resolution until saturated. A test is supplied. 2026-03-31 21:35:33 +02:00
Matthias Koefferlein f501f039c0 Added tests and two convenience methods 
The two convenience methods are

Library#library_from_file
Library#library_from_files

Both create and register a Library object tied to a file.
This object supports proper reloading and re-mapping on
"refresh".

Matthias Koefferlein 2dfcc9293e Allowing to explicity specify a format 
Most tools and functions now allow to explicitly
specify a format for input and output. On input,
the format is usually detected, but for some
cases, this is not possible (e.g. DEF). So you can
specify the format attached to the file name in
square brackets:

e.g. file.defok[def]

"def" is the intended suffix, "defok" is the given one.

On output, the same is possible, specifically in strmxor
and strmclip:

strmxor a.gds b.gds out.xor[oas]

Matthias Koefferlein 42a008efd1 Potential performance improvement for deep-mode DRC 
The idea is to use broken regions for certain operations
such as booleans in deep mode (local operations). These polygons are
more efficient. To support this, a "broken polygon" view
is supplied similar for "merged" view. The translation is
handled automatically.

As a side effect, regions may appear to be composed in broken
polygons now when they have been merged before.

Matthias Koefferlein 4b79c4c362 Fixing backward compatibility issue with pseudo-labels 
Problem: pseudo-labels are represented by polygons with
properties. If those get merged onto normal polygons
with "join_properties_on_merge", these are regarded
labels and translated to texts later. We avoid this
by skipping all objects with pseudo-label properties
on region merge in "join_properties_on_merge" mode.
