e.g. ``` .. autocell:: $alu :source: :linenos: ```
Fix RTD not including source with warning `WARNING: invalid signature for autocellsource ('/home/docs/checkouts/readthedocs.org/user_builds/yosys/checkouts/manual-rewrite/source/generated/simlib.v:$alu::__source')`.
Use autodocs to perform cell reference docs generation instead of generating rst files directly. e.g. ``` .. autocell:: simlib.v:$alu :source: :linenos: ```
