Software

The software framework has a modular structure that reflects the firmware and adds extra layers to make hardware interface user friendly. It loosely follows Register Abstract Layer (RAL) concepts. All the layers are automatically created based on yaml configuration file.

Yaml configuration file

TBD

Transfer Layer (TL)

Implements communication interface like UART, USB, Ethernet or Simulation. Every TL interface implements 2 functions:

class basil.TL.TransferLayer.TransferLayer(conf)

Transfer Layer implements minimum API needed access to hardware. On error raise IOError.

init()

Initialize and connect to hardware.

read()

Read access.

Return type

None

write(data)

Write access.

Parameters

data (iterable) – array/list of bytes

Return type

None

Hardware Layer (HL)

Implements drivers for basil modules and external devices. Drivers can reference other drivers within HL.

Register Layer (RL)

Implements Register Level Abstraction. Allow to user/control software to work on DUT registers without taking thinking about underlying levels.
