cspdk.si220.cband.cells.trans_rib50(*, length=50, width1=0.5, width2=0.5, w_slab1=0.2, w_slab2=10.45, cross_section='strip')#

A taper between strip and ridge.

This is a transition between two distinct cross sections

Parameters:

length (float) – the length of the taper.
width1 (float) – the input width of the taper.
width2 (float) – the output width of the taper.
w_slab1 (float) – the input slab width of the taper.
w_slab2 (float) – the output slab width of the taper.
cross_section (CrossSection | str | dict[str, Any] | Callable[[...], CrossSection] | SymmetricalCrossSection | DCrossSection) – a cross section or its name or a function generating a cross section.

Return type:

via_stack_heater_mtop#

cspdk.si220.cband.cells.via_stack_heater_mtop(size=(20.0, 10.0))[source]#

Rectangular via array stack.

You can use it to connect different metal layers or metals to silicon. You can use the naming convention via_stack_layerSource_layerDestination contains 4 ports (e1, e2, e3, e4)

also know as Via array http://www.vlsi-expert.com/2017/12/vias.html

Parameters:: size (tuple[float, float]) – of the layers.
Return type:: Component
