Highlighting the difference between `select prod %ci` and `select prod %ci2` by
introducing `sumproud.out` using the `dump` command.
Playing around with advanced cone example code.
Also adds `docs/tests/macro_commands.py` which checks all commands in
`code_examples/macro_commands` against the current yosys build. Format similar
to `run-test.sh` files: logging the file under test and reporting errors.
Adds two new `show` commands to `fifo.ys` for demo purposes.
Mention referencing named selections with `@<name>`.
Also adds a note to `example_synth` to point to the show intro.
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.
More `literalinclude` and references to source.
Adding `example_show.ys` and `example_lscd.ys`.
Rename `example_00` et al to `example_first` et al.
Also some other minor tidying.
Filling out the hardware mapping sections, and actually highlighting the changes in schematics instead of just the memory block.
Also includes Part 4 of the coarse-grain rep, looking at `memory_collect` and putting the `synth_ice40 -top fifo -run :map_ram` command in its own (sub)section.
Includes a `no_rw_check` section label in `memory.rst` for reference (because I can't remember how to reference by heading).
Not sure about the opt output after map_ram section which has an open TODO, and the final steps section is also still open.
Split hardware mapping from `fifo.ys` into `fifo_map.ys`. Reduces size of `fifo.out` log and allows separate yosys calls in the makefile.
Some tidy up and minor changes in `fifo.ys` for better discussion.
Filled out note on `clean` (changed from `opt_clean`) and introduced `;;`.
Highlighted `$memrd` and added a paragraph about it.
More detail on the flatten and merging of `fifo_reader` block.
Brief discussion on the changes from `$memrd` to `$memrd_v2`.
Split coarse grain representation into 4 parts, loosely: fsm/opt, other optimizations/techmap/memory_dff, DSPs, alumacc/memory -nomap.
Split hardware mapping into subsections as well: memory blocks (map_ram and map_ffram), arithmetic (map_gates), FFs (map_ffs), LUTs (map_luts and briefly abc), and other (map_cells and a note on hilomap and iopadmap).
Also add `-T` flag to Yosys call to remove footer from log output.
Added highlighting in (most) schematics.
Written down to end of coarse-grain, with a couple of TODOs for filling in gaps.
Includes `techmap_synth.rst` stub.
Fifo code based on SBY quick start.
Instead of showing the full design we are (currently) focusing on a single output (rdata), using `%ci*` to get the subcircuit it relies on.
Updates code examples, removing `counter_outputs.ys` in favour of a single script. Also adds a .gitignore for the output file `synth.v`.
`example_synth.rst` still pending updated example.
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.
Replace `typical_phases.rst` and `examples.rst` with a single `example_synth.rst`.
Also updating the counter example to match.
Aims to reduce redundancy, and simplify the getting started section.
Details on things like `proc`, `memory` and `fsm` should instead be in the advanced section (under the new `synth` subsection).
Makefiles now have `clean` target.
Also fixed top level makefile calls to images directory.
More yosys scripts instead of inline yosys commands in makefiles (which also means they can be included in the accompanying document when talking about the image generated).
Fixed another couple image generators that were still outputting pdf directly.
Fixed some hanging image references which hadn't been updated.
Adjusted some text related to images, and included a couple more intermediate images on `memdemo`.
see also previous commit
Also updates `scripting_intro.rst` to use literal includes, and uses individual image outputs to avoid the intermediary `.tex` file to join them all.
Code now resides in `docs/source/code_examples`.
`CHAPTER_Prog` -> `stubnets`
`APPNOTE_011_Design_Investigation` -> `selections` and `show`
`resources/PRESENTATION_Intro` -> `intro`
`resources/PRESENTATION_ExSyn` -> `synth_flow`
`resources/PRESENTATION_ExAdv` -> `techmap`, `macc`, and `selections`
`resources/PRESENTATION_ExOth` -> `scrambler` and `axis`
Note that generated images are not yet configured to build from the new code locations.
