Exit MiG, Enter LiteDRAM

  Really nice to see Verilator mentioned, since I worked with (in fact was recruited by) its primary author for a job a while ago. That is a really under-appreciated piece of open-source software, along with SimH which that company also used. Those were fun times indeed.

    Using both Verilator AND SimH? Can you tell us more about the job? That sounds awesome.

      The company was SiCortex, and I was there in 2007-2008. Didn't just use those two bits of software but employed their primary authors. High density of compute to power or space, based on a home-grown MIPS variant called Ice9. The first machines did OK - on the Green500 list, installed at a bunch of interesting places - but funding for the second generation didn't happen because it was 2008, so the end was very abrupt. A shame, really, because they were way ahead of their time and a lot of what they were doing would still be a good idea. Oxide comes closest, I guess, but not really that close. A real highlight of my career TBH.

  The size difference seems quite significant. Why is the Xilinx code so much bigger? Are there any significant limitations LiteDRAM has?
