- 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`.

Packaged ``synth_*`` commands
|

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
The following is a list of all synth commands included in Yosys for different
|
|
platforms. Each command runs a script of sub commands specific to the platform
|
|
being targeted. Note that not all of these scripts are actively maintained and
|
|
may not be up-to-date.

General synthesis
|
|
~~~~~~~~~~~~~~~~~
|
|
|
|
In addition to the above hardware-specific synth commands, there is also
|
|
:doc:`/cmd/prep`. This command is limited to coarse-grain synthesis, without
|
|
getting into any architecture-specific mappings or optimizations. Among other
|
|
things, this is useful for design verification.
|
|
|
|
The following commands are executed by the :cmd:ref:`prep` command:
|
|
|
|
.. literalinclude:: /cmd/prep.rst
|
|
:start-at: begin:
|
|
:end-before: .. raw:: latex
|
|
:dedent:
|
|
|
|
:doc:`/getting_started/example_synth` covers most of these commands and what
|
|
they do.
