Synth commands
--------------
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.
