Packaged ``synth_*`` commands
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

.. todo:: are all these synth commands supported?

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.

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:

The following sections will get more into what each of these commands do.
