bust bus tool

Utility for simply creating and modifying VHDL bus slave modules.

Concept

The main goal of the project is to able to automatically create and modify VHLD bus slave modules based on a simple definition format. By employing VHDL records the handling of the registers can be completely hidden in a module seperate from the rest of the designers logic. All referring to the registers are done via a record which specifies if the register is read-only or read-write, and also includes the name. All bus-specific signals are also wrapped in records. This increases the readability of the design as a whole.

Bus support

bust currently supports these bus-types:

Requirements

bust is thoroughly tested with python 3.6.8 but should work with the following versions:

  • python 3.4
  • python 3.5
  • python 3.6
  • python 3.7
  • python 3.8

bust does NOT support python 2.7 and neither should you!

Getting Started

Install the latest relase by using pip:

pip install bust

Usage

bust.py FILE [-o DIR]

bust.py --version

bust.py -h | --help

Examples

The examples folder contains JSON-files for the bus types supported. The files are human readable to the point that you can create your own from this template alone. The folder also contain the output files generated based on the JSON-files.

Simulation

Simulations script are made solely for Modelsim/Questasim. For any other simulators you need to compile everything yourselves. All testbenches require UVVM - which can be cloned from their Github page.

IPBus

IPBus require the bus package file from the IPBus firmware repo and the custom IPBus BFM repo made by me. Both can be cloned from their own repos.

See the example files for how you point to the specific folders.

Latest Development Version (Bleeding Edge)

The latest development version can be found in the dev branch on Github. Clone the repo and checkout the branch.

git clone https://github.com/olagrottvik/bust.git

cd bust

git checkout dev

pip install -r requirements.txt

python -m bust
