Manage HDL code as components so they can shared as IP.
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.
- 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
- 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
You can get the latest released version of HCM via pip.
