Changelog#

Unreleased#

0.2.0 - 2026-02-15#

Deprecated#

  • Fixed-GDS cells (*_fixed) are now deprecated in favour of the equivalent pure-Python parametric cells. They remain available but will be removed in a future release.

Added#

  • Pure GDSFactory RF-MOSFETs (nfet_rf, pfet_rf) with full layout generation, split from the transistors module #90

  • TechIHP Pydantic model centralizing all FET + RF geometry design-rule constants #90

  • cells2 PyCell reference page in documentation, documenting the CNI-ported reference implementations

  • Technology page (docs/tech.rst) documenting ihp.tech: layer map, layer stack, design rules, cross-sections, and routing strategies

  • 5 GHz up-converter mixer demo (mixer5ghz) added to documentation

  • Palace EM simulation notebooks added to docs #80

  • Scheme-to-YAML tools and source netlist converter #87

  • SPICE-to-YAML converter module with examples #84

  • 160 GHz LNA design example #71

  • Port overlap test #94

  • make docs-clean and make docs-serve targets for local doc previewing

Changed#

  • Documentation restructured: “PDK Reference” section with separate pages for parametric cells, deprecated fixed cells, and cells2 reference

  • Documentation generation script now produces three RST pages instead of one

Fixed#

  • Port layers now use pin sublayers with port_type="electrical" across all cells #94

  • Double _fixed_fixed naming bug on cmim_fixed and inductor2_fixed

  • MOSFET layout improved and fuzzed against PyCell reference #88

  • import_gds (functools.partial) no longer leaks into the cell catalog documentation

Removed#

  • Obsolete bipolar.py and transistors.py shims
