class bag3_magnetics.layout.inductor.util.IndLayoutHelper(temp_db: bag.layout.template.TemplateDB, params: bag.util.immutable.Param, **kwargs: Any)[source]

Bases: bag.layout.template.TemplateBase

classmethod get_params_info() → Mapping[str, str][source]

Returns a dictionary from parameter names to descriptions.

Returns:

param_info – dictionary from parameter names to descriptions.

Return type:

Mapping[str, str]

draw_layout() → None[source]

Draw the layout of this template.

Override this method to create the layout.

WARNING: you should never call this method yourself.
