Matthias Koefferlein 1de28f2d6b Refactoring, some enhancements to tl::Variant 
- Split binary and regular streams
- Binary serialization of tl::Variant
- Fixing tl::Variant parsable string representation for byte arrays and char
  (Format is '...'b for byte arrays and '.'c for chars).
- tl::to_quoted_string now allows 0 characters in the string
  (escapes to '\000')

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 ddb261d708 Improving stability of library refresh 
1.) Safeguard against missing cells
2.) Use topological order during refresh
    This avoid child-first issues
3.) Use cell names and basic names for mapping
    (cell names may be disambiguated while
    basic names are not)

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 95f2335fc4 [consider merging] bugfix: DeepRegion::processed with properties did not deliver polygon refs which made them unsuitable for further processing. 2026-03-19 12:53:30 +01:00

Matthias Koefferlein fb2559bf75 Fixing a performance regression in the merged layer computation 
Problem was that while properly implementing the reverse
cluster connection during cluster merges, cluster connection
propagation suffered a complexity explosion during generation
of the cluster interactions.

Solution is to postpone the cluster joining step until
a cell is finished connecting the clusters. To mitigate the
performance effect of that, some optimizations are
introduced (e.g. using a more efficient unordered_map).

Matthias Koefferlein c14d8cc877 [consider merging] proper cleanup of properties repo - this enables using user classes for names or values. Without this pre-finalization cleanup, the user class 'destroy' method may end up calling a method of an already destroyed class object. 2026-02-24 19:17:01 +01:00
Matthias Koefferlein bc49082955 Fixing a small glitch: drawing into a ghost cell is possible, but did not turn off the ghost cell flag. Now the flag is still on, but a non-empty cell is not considered a ghost cell for most purposes. 2026-02-19 23:26:48 +01:00
Matthias Koefferlein a8119c5a53 Performance improvement for hierarchical processor 
Problem was pushing of the results into the cell hierarchy
somehow lead to thread stalling. Likely due to bbox invalidation
and related effects. Solution is to store the results of
the operations inside the context structure (along with the
propagation information) and push it to the layout later in
a single step.
