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 c03a617fe2 Added some tests for the netlist browser API 2026-03-23 21:42:49 +01:00
Matthias Koefferlein 1588e74873 Providing a way to generate netlist browser paths 
You can generate paths from net, device, circuit or subcircuit
objects. To generate a path for an object from the first netlist
of a pair (layout netlist in LVS case), use

  NetlistObjectsPath#from_first

e.g.

  path = RBA::NetlistObjectsPath::from_first(net)

For an object from the second netlist (schematic in the LVS case)
use "from_second".

Matthias Koefferlein c211925d2a Implemented solution for #2306 
First of all, NetlistBrowserDialog#current_path now has a setter.
Changing the selection will navigate to the location of the
selected object, but not issue an "on_selection_changed" event.

In addition, the following features have been added:
* NetlistBrowserDialog#db_index
* NetlistBrowserDialog#view
 2026-03-21 20:32:32 +01:00
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 cb9e25f1b3 Issue #2300: added documentation about KLAYOUT_DEF_FORMAT and KLAYOUT_LEF_FORMAT environment variables. 2026-03-21 09:25:17 +01:00
Matthias Koefferlein c311906298 Some refactoring 2026-03-20 16:58:53 +01:00
Matthias Koefferlein 94908162d6 LEF/DEF suffixes can be configured 
The way to specify them is through the following
environment variables:

$KLAYOUT_LEF_FORMAT - LEF suffixes (default: "*.lef *.LEF *.lef.gz *.LEF.gz")
$KLAYOUT_DEF_FORMAT - DEF suffixes (default: "*.def *.DEF *.def.gz *.DEF.gz")

The string is a space-separated list of simple
match pattern. Only "*.xyz"-style pattern are allowed
currently.
 2026-03-20 16:48:35 +01:00
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 00c826688f Added the ability to run DRC and LVS from strmrun 2026-03-20 15:48:58 +01:00
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).

 2026-03-01 23:25:08 +01:00
Matthias Koefferlein aaa165df32 Providing a solution for #2248 
The solution is to introduce a new object, the layout handle.
A layout handle is a reference counting pointer to a layout.
It can be obtained from a cell view and stored somewhere.
If the cell view is closed, the layout will still exists
as long as a layout handle exists. A layout handle can be
used in LayoutView#show_layout in addition to the Layout
object to re-open a layout that existed in a closed view.

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 95d6b0aca5 Fixing a potential segfault during drawing 
This patch moves a lock inside the thread finishing
code such that a race condition of the finish sequence
and a random restart of the threads becomes impossible.
This problem has been observed while randomly zooming
with multiple drawing threads present. It's hard to
reproduce.

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.

1. The script API "map_file" attribute has been changed
   to accept and supply nil (for no file), a string (for
   a file, empty is equivalent to "no file") and a list
   for multiple files which are merged. The split at "+"
   or "," has been dropped.
2. The strm* tools option ("--lefdef-map") has been changed
   to allow multiple occurances instead of split at "+" or ",".

1. In deep mode, the count report column will report

2. XOR is shortcut evaluated with one empty input. The
   default implementation does that internally, but at
   the cost of mapping to the internal working layout
