The base template class. |
- class bag3_analog.layout.res.termination.Termination(temp_db: bag.layout.template.TemplateDB, params: bag.util.immutable.Param, **kwargs: Any)[source]
Bases:
xbase.layout.res.base.ResArrayBase
An array of resistors to be used as a termination. Resistors are connected in parallel in the X direction (horizontally), series in the Y direction (vertically).
Use export_mid to use as a differential termination
Assumption - Top layer is a horizontal layer
TODO: make the series / parallel direction a parameter.
- classmethod get_schematic_class() Optional[Type[bag.design.module.Module]] [source]
- classmethod get_params_info() Mapping[str, str] [source]
Returns a dictionary from parameter names to descriptions.
- classmethod get_default_param_values() Mapping[str, Any] [source]
Returns a dictionary containing default parameter values.
Override this method to define default parameter values. As good practice, you should avoid defining default values for technology-dependent parameters (such as channel length, transistor width, etc.), but only define default values for technology-independent parameters (such as number of tracks).
- Returns:
default_params – dictionary of default parameter values.
- Return type:
Mapping[str, Any]
- class bag3_analog.layout.res.termination.TerminationTop(temp_db: bag.layout.template.TemplateDB, params: bag.util.immutable.Param, **kwargs: Any)[source]
Bases:
bag.layout.template.TemplateBase
The base template class.
- Parameters:
temp_db (TemplateDB) – the template database.
params (Param) – the parameter values.
log_file (str) – the log file path.
log_level (LogLevel) – the logging level.
**kwargs (Any) –
dictionary of the following optional parameters:
- gridRoutingGrid
the routing grid to use for this template.
- classmethod get_schematic_class() Optional[Type[bag.design.module.Module]] [source]
- classmethod get_params_info() Mapping[str, str] [source]
Returns a dictionary from parameter names to descriptions.
- 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.
