Verilator is great and I use it all the time and it is critical for my project. Thanks again to all of you on the verilator team. I am running Ubuntu. $ uname -srvo Linux 6.2.0-39-generic #40~22.04.1-Ubuntu SMP PREEMPT_DYNAMIC Thu Nov 16 10:53:04 UTC 2 GNU/Linux My verilator install is from August 2020, so I followed your instructions to update on Ubuntu on your web page: $ sudo apt-get update ... $ sudo apt-get install verilator ... verilator is already the newest version (4.038-1). As you can see, that's hardly the latest version. Daniel

@dsw packaging in Ubuntu repositories is the responsibility of the Ubuntu maintainers. If you want to update to the most recent version you should follow the instructions in the Verilator documentation to build from source.

[dsw]

I just thought you might want to know. I suppose the Ubuntu maintainers have not noticed in several years. I don't know any of them or I would ping them.

@dsw Verilator, just like almost all other packages, do not get version updates in a stable release of a distribution like Ubuntu (even though in the case of Ubuntu 22.04 the version was already old by the April 2022).

You can find the package maintainer contacts at https://packages.ubuntu.com/search?keywords=verilator, then choose the version you're using, i.e. https://packages.ubuntu.com/jammy/verilator

In case of Verilator, the packaging is done by the Debian Electronics team, and Ubuntu imports those packages. https://alioth-lists.debian.net/pipermail/pkg-electronics-devel/2024-January/thread.html is the place to discuss the packaging and to help out (it's actually not that hard and a great way to get started as a contributor!)
