- 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.
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.
- 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`.
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.
This is mostly useful for collecting coverage for the future `$check`
cell, where, depending on the flavor, formatting a message may not be
wanted even for a failed assertion.
The behavior of these format specifiers is highly specific to Verilog
(`$time` and `$realtime` are only defined relative to `$timescale`)
and may not fit other languages well, if at all. If they choose to use
it, it is now clear what they are opting into.
This commit also simplifies the CXXRTL code generation for these format
specifiers.
The primitives used have been corrected and changes have been made to the set of signals.
The empirically established need to set the OCEx signal to 1 when using READ_MODE=0 is reflected.

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.
At the moment the only thing it allows is redirecting `$print` cell
output in a context-dependent manner. In the future, it will allow
customizing handling of `$check` cells (where the default is to abort),
of out-of-range memory accesses, and other runtime conditions with
effects.
This context object also allows a suitably written testbench to add
Verilog-compliant `$time`/`$realtime` handling, albeit it involves
the ceremony of defining a `performer` subclass. Most people will
want something like this to customize `$time`:
int64_t time = 0;
struct : public performer {
int64_t *time_ptr;
int64_t time() const override { return *time_ptr; }
} performer = { &time };
p_top.step(&performer);
