Latch-Up is a conference dedicated to open-source silicon organized by the FOSSi Foundation. At Latch-Up 2025 in Santa Barbara, CA, I presented a Chisel Update, primarily focused on the recent v7.0.0-RC1 release. There were lots of other interesting talks, check out the full schedule which includes links to the recordings and slides for each talk: https://fossi-foundation.org/latch-up/2025.

Two talks in particular that I think might interest the Chisel community:

• Rachit Nigram's talk High-Performance Hardware Design with Hardcaml--In this talk Rachit does a great job of helping explain the intuition of how one might build an eDSL (embedded domain specific language) like Chisel.
• Xiaoke Su's talk "One Student One Chip" Initiative: Learn to Build RISC-V Chips from Scratch with MOOC--This talk is about thousands of students learning hardware design; apparently over half of the students choose to use Chisel which is pretty cool.

Feel free to start a discussion on Github or chat with us on Matrix if you have any questions or thoughts about the talk.

It's been many years since the Chisel project had a blog. In the spirit of New Year's resolutions (and more pragmatically as a means to better communicate with the open source community about Chisel), the Chisel developers are restarting the blog.

In the future look for posts by Chisel users and developers about new features, the rationale behind existing features, and more communication about the broad direction of Chisel.
