Backward compatibility
|
|
|
|
|
======================
|
|
|
|
|
|
|
|
|
|
OpenFPGA v1.1
|
|
|
|
|
-------------
|
|
|
|
|
|
|
|
|
|
OpenFPGA v1.2 is a major upgrade over v1.1, which upgrades the internal VPR engine.
|
|
|
|
|
The (VPR) architecture files used with v1.1 may not be compatible with v1.2.
|
|
|
|
|
|
|
|
|
|
You can upgrade your architecture files with script
|
|
|
|
|
|

|
|
|
.. code-block:: bash
|
2022-12-06 16:07:29 -06:00
|
|
|
|
|
|
|
|
python3 openfpga_flow/scripts/arch_file_updater.py \
|
|
|
|
|
--input_file ${v1.1_arch_file} \
|
|
|
|
|
--output_file ${v1.2_compatible_arch_file}
|
|
|
|
|
|
|
|
|
|
Or, If you want to stay with v1.1, the final build was (tag: `OpenFPGA:v1.1.541 <https://github.com/lnis-uofu/OpenFPGA/tree/v1.1.541>`_))
