HDL Component Manager

Project description

Manage HDL code as components so they can shared as IP.

Github Release PyPI Version Build Status Test Coverage Read The Docs Codacy Maintainability docs/img/hcm_overview.gif

Overview

HCM was created after a frustrating attempt to merge changes from one program to another. Even after carefully performing the merge, there were issues.

It was turning into a nightmare just to pass updates between multiple concurrently running programs. I was inspired by PIP, and how easy it is to install python packages. I wanted to bring that same level of ease to HDL design.

Key Benefits

  • Provides a method to control versions of IP
  • Controls the distribution of HDL code
  • Follows the Major.Minor.Patch method of version control
  • Language independent (VHDL, Verilog, System Verilog)
  • Can be used to control vendor IP

Key Features

  • Works with SVN repositories
  • Automates publishing of code to a central location
  • Automates installing and upgrading of code
  • Supports multiple IP repositories
  • Supports dependencies between components

Installation

You can get the latest released version of HCM via pip.

pip install hcm

The latest development version can be cloned…

git clone https://github.com/jeremiah-c-leary/hdl-component-manager.git

…and then installed locally…

python setup.py install

HCM can be invoked by issuing hcm at the command line prompt:

$ hcm
usage: hcm [-h]
           {browse,create,download,install,uninstall,list,publish,show,validate,version}
