Create AWS Palace FEM Models from GDSII layout files
The files provided here enable RFIC FEM simulation using AWS Palace from GDSII layouts created in IHP SG13G2 RFIC technology.
Palace, is an open-source, parallel finite element code for full-wave 3D electromagnetic simulations. It can be scaled from single computer to large high performance simulation clusters and cloud-based computing.
https://awslabs.github.io/palace/stable/
In addition to AWS Palace, gds2palace can also generate models for Elmer FEM, as an additional workflow option for EM (S-parameter) simulation as well as steady-state thermal simulation. See CHANGES.md for this and other recent additions.
The gds2palace workflow in this repository is pre-configured for GDSII layout files in the IHP SG13G2 Open PDK. Special thanks to IHP and the public funded German project FMD-QNC (16ME0831) https://www.elektronikforschung.de/projekte/fmd-qnc for financial support, which has contributed to this work.

Recent changes
0.7.0 (25-26 September 2026)
settings['fill_factor_correction'] is a new option for improved accuracy when using via array merging (merge_polygon_size > 0). Merging fills the gaps between vias with via material, so the merged via block has a larger cross section and lower resistance than the real via array. With this option, each merged via polygon's conductivity is multiplied by its fill factor (original via area / merged polygon area). It applies to Palace and to Elmer (EM and thermal) and is not active by default.
API change: gds_polygon.is_via and the is_via parameter of all_polygons_list.add_rectangle()/add_polygon() were removed: they were never set when reading GDSII and never used. Scripts that pass is_via= to these functions need to drop that argument.
0.6.0 (22-23 September 2026)
settings['filled_metals'] is a new option for Palace: volume meshing inside conductors instead of a surface impedance on the conductor surfaces. This gives more accurate conductor loss at low frequency, where the skin depth is no longer small compared to the conductor cross section. It is not the recommended default, because it needs more RAM and simulation time.
settings['adaptive_mesh_conformal'] is a new experimental option (default False) for conformal instead of non-conformal (hanging node) adaptive mesh refinement.
combine_extend_snp.py now handles an interrupted Palace run (e.g. stopped by a memory limit): missing S-parameters are written as 0.0 dB / 0 deg with a warning, instead of crashing or writing invalid Touchstone data.

Note: the gds2palace PyPI package itself only requires:
- gdspy>1.6.0
- gmsh
- numpy
- shapely>=2.0
(Other Python modules mentioned above are only needed to run the example/model scripts in this repository, not to use the installed package.)
