      I was given a tour through ALS (https://als.lbl.gov/ ) the other day. Pics on my Instagram: https://www.instagram.com/p/BbzXsqkDkOg/  Fun Note: They use PicoRV32 in interlocks. This makes LBNLs ALS the second particle accelerator to use one of my projects (CERNs LHC is using LibXSVF).pic.twitter.com/5ahoKSSa6f

      Company engineer: "I would never use Open Source HDL code as I don´t have assurance about its quality. With commercial IP, I get commercial grade support." National Lab: "I don´t care. I need this thing to work. I take whatever works."

      Interlocks are a critical safety feature of a machine like that. They explicitly told me that they were impressed with the amount of verification that went into PicoRV32. I guess here the argument is: With OSHW we see how it is verified, with comm IPs we can only trust vendor.

          "commercial IP is supported" I literally have not once gotten any helpful support from xilinx for where their synthesis doesn't play nice and I can't fix their synthesis because the whole process is opaque

          This is an argument I have been making for many years. With closed source you often buy the expectation that is good, without proof

          I'm always impressed with the "comercial grade" bs. I saw "comercial grade source code" in the past, it wasn't a masterpiece :)
