• box_plus_buffer (bool, optional) – Whether or not to use a box plus buffer. Defaults to True.

render_component(component)

Abstract method. Must be implemented by the subclass. Render the specified component.

Parameters:

component (QComponent) – Component to render.

render_components(table_type: str, layer_num: int, port_list: list | None, jj_to_port: list | None, ignored_jjs: list | None)

Render components by breaking them down into individual elements. Render all components of the design. If selection is none, then render all components.

Parameters:

table_type (str) – Table type (poly, path, or junction).

render_design(selection: list | None = None, open_pins: list | None = None, port_list: list | None = None, jj_to_port: list | None = None, ignored_jjs: list | None = None, box_plus_buffer: bool = True)

This render_design will add additional logic for just eigenmode design within project.

Initiate rendering of components in design contained in selection, assuming they’re valid. Components are rendered before the chips they reside on, and subtraction of negative shapes is performed at the very end.

First obtain a list of IDs of components to render and a corresponding case, denoted by self.qcomp_ids and self.case, respectively. If self.case == 1, all components in QDesign are to be rendered. If self.case == 0, a strict subset of components in QDesign are to be rendered. Otherwise, if self.case == 2, one or more component names in selection cannot be found in QDesign.

Chip_subtract_dict consists of component names (keys) and a set of all elements within each component that will eventually be subtracted from the ground plane. Add objects that are perfect conductors and/or have meshing to self.assign_perfE and self.assign_mesh, respectively; both are initialized as empty lists. Note that these objects are “refreshed” each time render_design is called (as opposed to in the init function) to clear QAnsysRenderer of any leftover items from the last call to render_design.

Among the components selected for export, there may or may not be unused (unconnected) pins. The second parameter, open_pins, contains tuples of the form (component_name, pin_name) that specify exactly which pins should be open rather than shorted during the simulation. Both the component and pin name must be specified because the latter could be shared by multiple components. All pins in this list are rendered with an additional endcap in the form of a rectangular cutout, to be subtracted from its respective plane.

The final parameter, box_plus_buffer, determines how the chip is drawn. When set to True, it takes the minimum rectangular bounding box of all rendered components and adds a buffer of x_buffer_width_mm and y_buffer_width_mm horizontally and vertically, respectively, to the chip size. The center of the chip lies at the midpoint x/y coordinates of the minimum rectangular bounding box and may change depending on which components are rendered and how they’re positioned. If box generated with box_plus_buffer passes the chip size, the box will be cropped to chip size. If box_plus_buffer is False, however, the chip position and dimensions are taken from the chip info dictionary found in self.design, irrespective of what’s being rendered. While this latter option is faster because it doesn’t require calculating a bounding box, it runs the risk of rendered components being too close to the edge of the chip or even falling outside its boundaries.

Parameters:

• selection (Union[list, None], optional) – List of components to render. Defaults to None.

• open_pins (Union[list, None], optional) – List of tuples of pins that are open. Defaults to None.

• box_plus_buffer (bool, optional) – Either calculate a bounding box based on the location of rendered geometries or use chip size from design class.
