Most of the word/coarse level cells have an assigned group and individual page.
The gate/fine level cells are all on one page.
Fix links to `cell_library.rst`.
- Use `:file:` role for file names, as well as `:makevar:` and `:program:`.
- Remove deprecated `linux-arm` and `linux-riscv64` oss-cad-suite targets.
- Add link to ABC.
- More (and better) links to code examples. Formatted `:file:` text with link
to source on github.
- Includes a few extra todos (mostly picking up inline code blocks and a couple
intro reminders).
- Fixing a few missing `:yoscrypt:` and `:cmd:ref:` tags.
- Reflowing some paragraphs for spacing/width.
- Filling out index descriptions for `using_yosys` and `using_yosys/synthesis`.
- To discourage skipping over these index pages, the toctree in
`using_yosys/index` is hidden and instead has inline links to the two
subsections.
- Tidying todos.
- Moves technology mapping to `techmap_synth`, leaving the techmap by example in
the internals section. `yosys_flows` gets split up, with the coarse-grain
intro replaced by `synthesis/index`, the extract pass moving to
`synthesis/extract` and model checking to `more_scripting/model_checking`.
Now comes *after* example_synth, with references back to it.
Includes some minor adjustment to the `fifo.ys` script to better demonstrate the `select` command.
Still needs an updated section on `show`.
Also includes some other minor updates.
Replace leftover `opt` example source/images with examples specific to the `opt_*` pass.
Currently has images for `opt_expr`, `opt_merge`, `opt_muxtree`, and `opt_share`.
Also includes some other TODO updates.
Overall structure in place to match the iCE40 flow.
Still needs a new example design, and more text for the later sections (which the counter doesn't cover).
Moved the last files out of the resources directory.
Some tidy up/reformatting of the extensions to allow literalincludes from `my_cmd.cc`.
Most (all?) of the getting started guidelines file is either in the quick guide section, or sections referenced by it. Instead of including it verbatim, we'll instead just leave a reference to it but then jump straight into the quick guide.
Include an image for the absval generated module. Still needs more surrounding text but it's good enough for now.
Also includes some other minor tidying, including removing the no longer used abc_01 code example.
Includes comparison of `abc` v `abc9`. Also creates a new subsection of the
yosys internals for extending yosys (moving the previous extensions.rst into it).
