WireWaveguideTransitionFromPortLinear

class picazzo3.traces.wire_wg.WireWaveguideTransitionFromPortLinear

A linear transition between two WireWaveguideTemplates.

Parameters:

start_port: _PortInterface

the port on which to extract trace template, position and angle

end_trace_template: PCell and _TraceTemplate and WireWaveguideTemplate

start_trace_template: PCell and _TraceTemplate and WireWaveguideTemplate

name: String that contains only ISO/IEC 8859-1 (extended ASCII py3) or pure ASCII (py2) characters

The unique name of the pcell

Other Parameters:

reverse_templates: ( bool, bool_ or int ), locked

When True, treat start_trace_template as end_trace_template and vice versa. To use the correct templates, use the _{start/stop}_trace_template properties. This should not be set manually, but calculated by the transition itself.

Views

class Layout

Parameters:

straight_extension: Coord2 and number >= 0

tuple: straight extension at start and end of transition

length: float and Real, number and number >= 0

length of the transition

end_position: Coord2

end position of the transition

start_position: Coord2

start position of the transition

view_name: String that contains only alphanumeric characters from the ASCII set or contains _$. ASCII set is extended on PY3.

The name of the view

Examples

"""This example shows how to append a transition onto a component.

We define a PCell with a port on the Layout level (position + angle). Then we use
WireWaveguideTransitionFromPortLinear to connect this port to a transition that creates
a transition to a wire waveguide.
