How to install from sources and where is the doc about the commands?

[rodrigomelo9]

Hello. I want to know from which repository are the symbiflow tools (symbiflow_synth, symbiflow_pack, etc) generated. Also, I want their documentation. Is enough to point me to the right doc. Are Yosys+nextpnr+icestrom tools, for example, completely replaced by the symbiflow tools? (in this repository, there are only examples of Xilinx and QuickLogic).

Thanks, Rodrigo

@kgugala Could you help @rodrigomelo9 to find these?

@rw1nkler - I think this means we need some documentation updates?

Hi @mithro, thanks. In the meantime, are the commands symbiflow_synth, symbiflow_pack, etc, exactly the same as yosys, nextpnr (-ice40 or -ecp5, according to the case), etc? Or are they new binaries with any difference?

I think that this info is missing, and must be put somewhere at https://symbiflow.readthedocs.io/en/latest/toolchain-desc.html If I understand, I can help :-D I want to add Symbiflow to PyFPGA and add a small tutorial into FOSS for FPGA.
