SpinalHDL did not fork from Chisel. You might be able to say that it was inspired by Chisel, but it does not share a commit history. See this comment by the author: https://www.reddit.com/r/chisel/comments/4ivevd/comment/d3lj...

Thank you for the correction! My original comment is too old to update. It’s so frequently described as one (for example in https://github.com/SpinalHDL/SpinalHDL/issues/202#issuecomme... ) that I assumed they shared a history.
