SingleToDiff

The base template class.
class bag3_digital.layout.stdcells.se_to_diff.SingleToDiff(temp_db: bag.layout.template.TemplateDB, params: bag.util.immutable.Param, **kwargs: Any)[source]

Bases: xbase.layout.mos.base.MOSBase

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.

property buf_col_list: Sequence[int][source]
classmethod get_schematic_class() → Optional[Type[bag.design.module.Module]][source]
classmethod get_params_info() → Dict[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]

classmethod get_default_param_values() → Dict[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]

draw_layout()[source]

Draw the layout of this template.

Override this method to create the layout.

WARNING: you should never call this method yourself.
