MOSBaseWrapper	The base template class.
GenericWrapper	A MOSArrayWrapper that works with any given generator class.

class xbase.layout.mos.top.MOSBaseWrapper(temp_db: bag.layout.template.TemplateDB, params: bag.util.immutable.Param, **kwargs: Any)

Bases: bag.layout.template.TemplateBase, abc.ABC

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.

class xbase.layout.mos.top.GenericWrapper(temp_db: bag.layout.template.TemplateDB, params: bag.util.immutable.Param, **kwargs: Any)

Bases: MOSBaseWrapper

A MOSArrayWrapper that works with any given generator class.

classmethod get_params_info() → Dict[str, str]

Returns a dictionary from parameter names to descriptions.

Returns:

param_info – dictionary from parameter names to descriptions.

Return type:

Mapping[str, str]

classmethod get_default_param_values() → Dict[str, Any]

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]

get_layout_basename() → str

Returns the base name for this template.

Returns:

base_name – the base name of this template.

Return type:

str

draw_layout()

Draw the layout of this template.

Override this method to create the layout.

WARNING: you should never call this method yourself.

wrap_mos_base(master: xbase.layout.mos.base.MOSBase, export_hidden: bool, half_blk_x: bool = True, half_blk_y: bool = True) → None
