02.02.2021 - GHDL v1.0 was released

31.01.2021 - GHDL v1.0.0rc1 was tagged

• Python bindings were overhauled and renamed to pyGHDL. Three modules are included: libghdl, lsp and dom.
  • The utility scripts in the codebase were moved into subdir scripts: CI, binding generation, vendors, etc.
• Repository ghdl/extended-tests was created for testing vendors build scripts.
• The logo was updated (org, ghdl/ghdl, ghdl/docker and ghdl/ghdl-cosim).
• Assets are not added to releases or pre-releases anymore. Users should use package managers or nightly assets.

21.05.2020 - Nightly build assets available

• After each successful CI run of branch master, packages are published as assets of pre-release nightly.
• GitHub Action ghdl/setup-ghdl-ci was created, to allow easy installation of nightly GHDL assets in GitHub Actions workflows.

09.05.2020 - New repositories and a wiki were created

• The plugin for Yosys was moved from tgingold/ghdlsynth-beta to ghdl/ghdl-yosys-plugin.
• Repository ghdl/ghdl-cosim was created. It contains documentation and code examples related to VHPIDIRECT, VPI and SystemC. See COSIM and Previous work and future ideas.
• A Wiki was created. The roadmap and ideas for documentation and internship programs were moved there. If you want to contribute anyhow, have a look!

28.02.2020 - GHDL v0.37 was released

The major changes are:

• Experimental support of synthesis (either with --synth or with

the Yosys plugin).

• Fixes and improved support of vhdl 2008.
• Last version that supports the Mentor variation of

std_logic_arith. The Synopsys one is still available.

03.03.2019 - GHDL v0.36 was released

23.02.2019 - GHDL v0.36-rc1 was released

The major improvements are:

• more support of unbounded arrays and records
• support of UVVM and Vunit

29.11.2018 - GHDL 20181129 was released

20.12.2017 - A new GitHub organization was created

A new GitHub organization is created and the main repo is moved from github.com/tgingold/ghdl to github.com/ghdl/ghdl. Old refs will continue working, because permanent redirects are set up. However, we suggest every contributor to update the remote URLs in their local clones.

14.12.2017 - GHDL 0.35 was released

15.08.2017 - GHDL 0.34 was released

23.10.2015 - GHDL 0.33 was released
