  • Making OSVVM a Git Submodule by lasplund on August 08, 2016

    Prior to the 0.67.0 release the OSVVM library included with VUnit was a modified copy of the original project to support GHDL. Nowadays the OSVVM project supports GHDL natively and it is also available from GitHub so we made it a submodule instead. The submodule is a way to keep another Git repository (OSVVM) in a subdirectory of the VUnit repository while keeping their histories separate. Updates to OSVVM doesn’t affect the VUnit history and vice versa. This makes no difference if you’re downloading VUnit from PyPi but if you’re cloning VUnit from GitHub there are some things to consider. If you’re pulling version 0.67.0 to update your local Git clone the OSVVM subdirectory of VUnit will become empty. To populate the directory you have to do

  • Improving VHDL Testbench Design with Message Passing by lasplund on February 21, 2016

    Some time ago me and my colleagues at Synective Labs did a teamwork exercise called the Marshmallow Challenge. The challenge is to build the tallest structure that can hold a marshmallow from twenty sticks of spaghetti, one yard of tape and one yard of string. The structure must be completed within 18 minutes. Many teams with various backgrounds have taken this challenge and a number of observations have been made:

  • Website Updates by lasplund on February 01, 2016

    Our website has been updated with a Gitter-based chat and an improved documentation platform based on Sphinx. When changing to Sphinx it came natural to also switch the blogging platform to ABlog which is based on Sphinx.

    The chat has just been active for a few days but it’s already very active. Currently it’s used to port VUnit to Cadence Incisive. We don’t have such licenses but the chat has been used to support the porting work done by people that do. FOSS collaboration at its best!
