DigitalDesigner

Base class of all design scripts.

BinSearchSegWidth

Helper class that provides a standard way to create an ABC using
class bag3_digital.design.base.DigitalDesigner(*args: Any, **kwargs: Any)[source]

Bases: bag.simulation.design.DesignerBase, abc.ABC

Base class of all design scripts.

Notes

  1. This class hides the SimulationDB object from the user. This is because hierarchical designers share the same SimulationDB, and if you don’t make sure to update the working directory every time you run
