Changelog

Previous

[1.1.0] — 2026-06-04

Added

  • Public [add_route_from_corners_dbu][doroutes.add_route_from_corners_dbu] API for routing in database units (#126)
  • Backwards-compatible support for passing lengths in both microns and dbu (#120)

[1.0.0] — 2026-05-26

Changed

  • Breaking: standardized public API — routing and bundle functions use micron parameters, always return corners, and follow consistent naming (#115, #119)
  • [FanStrategy][doroutes.FanStrategy] TypedDict replaces loose keyword arguments for fan-in/fan-out configuration (#115)
  • Deprecation wrappers added for all renamed/removed parameters — old call sites emit warnings instead of breaking (#115)

[0.6.1] — 2026-05-21

Fixed

  • Use round() instead of int() for um-to-dbu corner conversion to avoid float truncation (#118)

Fixed

  • L-bend wire clearance (#91)
  • Collapse collinear corners so consecutive same-axis steps don't insert fake bends (#70)
  • Sbend fan-in radius calculation rewritten as per-wire angle euler s-bend (#55)
  • Remove PDK.activate() calls and cspdk dependency (#98)

Changed
