  • cross_section (CrossSection | str | dict[str, Any] | Callable[[...], CrossSection] | SymmetricalCrossSection | DCrossSection) – spec.

  • width (float | None) – optional width. Defaults to cross_section width.

Return type:

Component

from ihp import PDK, cells

PDK.activate()

c = cells.wire_corner(cross_section='metal_routing').copy()
c.draw_ports()
c.plot()

wire_corner45#

ihp.cells.wire_corner45(cross_section='metal_routing', radius=10, width=None, layer=None, with_corner90_ports=True)[source]#

Returns 90 degrees electrical corner wire.

Parameters:

  • cross_section (CrossSection | str | dict[str, Any] | Callable[[...], CrossSection] | SymmetricalCrossSection | DCrossSection) – spec.

  • radius (float) – ignored.

  • width (float | None) – optional width. Defaults to cross_section width.

  • layer (tuple[int, int] | str | int | LayerEnum | None) – ignored.

  • with_corner90_ports (bool) – if True, adds ports at 90 degrees.

Return type:
