Intel/Altera
============

.. NOTE::

  * C10LP-RefKit
  * DE0
  * de0nano

Loading a bitstream
-------------------

SVF and RBF files are supported.

``sof`` to ``svf`` generation:

.. code-block:: bash

    quartus_cpf -c -q 12.0MHz -g 3.3 -n p project_name.sof project_name.svf

``sof`` to ``rbf`` generation:

.. code-block:: bash

    quartus_cpf  --option=bitstream_compression=off -c project_name.sof project_name.rbf

.. WARNING::
  As mentioned in ``cyclone`` handbooks, real-time decompression is not supported by FPGA in JTAG mode.
  Keep in mind to disable this option.

You can have Quartus automatically generate SVF and RBF files by adding these lines to the ``qsf`` file, or include them in a ``tcl`` file in FuseSoC

.. code-block:: 

    set_global_assignment -name ON_CHIP_BITSTREAM_DECOMPRESSION OFF
    set_global_assignment -name GENERATE_RBF_FILE ON
    set_global_assignment -name GENERATE_SVF_FILE ON

file load:

.. code-block:: bash

    openFPGALoader -b boardname project_name.svf
    # or
    openFPGALoader -b boardname project_name.rbf

with ``boardname`` = ``de0``, ``cyc1000``, ``c10lp-refkit``, ``de0nano``, ``de0nanoSoc`` or ``qmtechCycloneV``.

SPI flash
---------

RPD and RBF are supported.

``pof`` to ``rpd``:

.. code-block:: bash

    quartus_cpf -c project_name.pof project_name.rpd

``sof`` to ``rpd``:

.. code-block:: bash

    # CYC1000
    quartus_cpf -o auto_create_rpd=on -c -d EPCQ16A -s 10CL025YU256C8G project_name.svf project_name.jic
    # C10LP-RefKit
    quartus_cpf -o auto_create_rpd=on -c -d EPCQ16A -s 10CL055YU484C8G project_name.svf project_name.jic

file load:

.. code-block:: bash

    openFPGALoader -b boardname -r project_name_auto.rpd
    # or
    openFPGALoader -b boardname -r project_name.rbf

with ``boardname`` = ``cyc1000``, ``c10lp-refkit``.

Loading a Serial Vector Format (.svf)
-------------------------------------

SVF files are supported.

To load the file:

 .. code-block:: bash

    openFPGALoader -c usb-blaster project_name.svf
