I would not recommend Chisel unless you have some experience in RTL design. Although it is less documented and has a smaller community, I find SpinalHDL to be quite a bit better (it's based on Chisel but has taken the idea a step further). Chisel allows you to make many obvious mistakes that will be hard to debug and fix unless you've already got some experience. SpinalHDL catches many design errors (with info resembling tracebacks in some cases) before you get to simulation or synthesis.
