  3. class DecoupledDriver[T <: Data] extends AnyRef
  4. sealed class Region extends AnyRef

    Base class for regions, akin to Verilog regions for ordering events between threads within the same timestep.

    Base class for regions, akin to Verilog regions for ordering events between threads within the same timestep. order is the order regions run in, with 0 being the default, and incrementing regions running later. TODO: have a more extensible ordering than ints.

    This is a simple tester that does not require that it be within the scope of a scalatest in order to run.

    This is a simple tester that does not require that it be within the scope of a scalatest in order to run. This form is suitable for running in the Jupyter notebook.
