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

python3 openfpga_flow/scripts/ \
    --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))

docker pull
