Dear enthusiasts of BSV and BH, I have some very sad news to share with you today. Our dear friend and colleague Prof. Arvind of MIT passed away this morning, after suffering from Myeloma for some years now. The central technical idea behind the Bluespec BSV and BH hardware design languages---expressing hardware behavior using atomic rules and compiling it to efficient Verilog---came out of research in the late 1990s by Prof. Arvind and his then PhD student James Hoe. A later important development in BSV/BH, "Ephemeral History Registers", or "Concurrent Registers", came out of research by Prof. Arvind and his then PhD student Daniel Rosenband. Arvind founded two companies---Sandburst (in 2000), and Bluespec, Inc. (in 2003)---based on those ideas. Some of us have been involved with these companies since 2000 (and still are). We shall miss Prof. Arvind dearly. Nikhil

We are pleased to announce the next official release of open BSC! Along with bug fixes and build improvements, this release includes initial support for automatic linking with Verilator and for using DPI instead of VPI for imported C functions. Source and binary distributions are available at https://github.com/B-Lang-org/bsc/releases/tag/2022.01 We use the convention YYYY.MM for naming releases and a release schedule of twice a year, in January and July. Therefore, users can expect a next release, 2022.07, in six months. Patch releases, if needed, will be named 2022.01.1, etc. Mid-cycle snapshots may also be tagged, if needed by developers.

A paper on BSC was accepted to WOSET, the Workshop on Open-Source EDA Technology! The conference will occur online on November 4th and is free to attend. Plus, the papers and presentations are already freely available to download from the conference website. If you're interested in open EDA or just want to see our paper, check it out: https://woset-workshop.github.io/WOSET2021.html The paper, written by folks at Bluespec Inc, is a whirlwind summary of the open BSC tools and a survey of open designs written using BSC, many of which are interesting open EDA tools in themselves. WOSET has run annually since 2018 and the papers from past years are all available on the website, as well as the video presentations and slides from last year: https://woset-workshop.github.io We'd love to hear about other venues, organizations, or initiatives around open EDA or open hardware. If you're involved with any, let us know!
