AsFigo - enabling opensource chip design and verification.

UVM on Verilator Isn’t Impossible. It’s Just Hard. We Did It Anyway. The “standard” line in the industry: UVM and Verilator don’t mix. Enterprise-grade open-source verification is a fantasy. So we put that claim under load. ✔ 50+ production UVCs ported ✔ 35 + non-obvious failure modes uncovered ✔ Converted into UVMLint and SVALint rules ✔ AI guardrails to prevent regressions This post is the why and what; the how and numbers are for the room at Hacker Dojo.  This is production-grade code—the kind that tapes out chips—running on open-source infrastructure. The implication is bigger than a port: Reduced dependency on closed ecosystems. Negotiating leverage with EDA vendors. Strategic control over your verification stack. If you’re a semiconductor company exploring Verilator for serious IP, don’t start from scratch. Start from the team that already mapped the minefield. 📅 Join us at the Hacker Dojo Next Thursday, the AsFigo team...

The transition of SystemVerilog UVM environments to open-source simulators presents specific technical challenges. While Verilator 5.0+ has expanded support for various SystemVerilog constructs, the industry still lacks a documented and repeatable path for certain UVM-specific behaviors. In parallel, we aim to curate a public vault of UVM repositories that have been successfully ported to Verilator. AsFigo is initiating a collaborative effort to document these gaps, and we are looking for engineers, researchers, and students to contribute original UVM codebases to this effort.  Link to Google Form: Submit Your code base The Technical Focus This effort intentionally moves beyond minimal or illustrative examples. We are seeking unique, original UVM implementations that reflect realistic UVM environments and non-trivial SystemVerilog usage found in real-world verification flows.

 So, here we are on Day-1 of UVM + Verilator becoming available to the public, start of democratizing chip design verification. In case you just woke-up/started on this topic, read the release of UVM + Verilator with some intricate details on the challenge on the way by Antmicro via:  https://antmicro.com/blog/2023/10/running-simple-uvm-testbenches-in-verilator/  Awesome work by the folks at Antmicro and fantastic support by the ecosystem specifically Western Digital, kudos!  At AsFigo , we are committed to fueling open-source driven chip design and verification. So we took this opportunity to port a commercial-grade UVC (Universal Verification Component or a Verification IP) and ported it to compile and run on Verilator. Below are our reflections from this experiment. Get in touch with us to discuss how AsFigo can help your VIPs and testbenches to be ported to opensource EDA.  Case study: VLBus - a simple peripheral bus intended for write/read to configuration...
