Question: `env` section problem. about fusesoc

[BaseHardware]

I think specifying the tool that I used is also important. It was vivado.

I think there might be something funky with env vars in scripts. Have a vague memory of this. Unfortunately don't have time myself to look into that right now. Maybe set it before running FuseSoC as a workaround?

@olofk Thanks for your reply. I share my understanding of this problem: When I tested this problem with the tool 'ghdl', the problem disappeared and it seems the problem is related to the behavior of edalize.

Although I don't know the exact reason, let me say the apparent reason: If I use 'ghdl', the script is executed through the _run_scripts of the edatool class, which sets the environmental variables and any other configurations properly with the core file, while in 'vivado', the script is executed through the 'pre_build' section of the generated Makefile in the build directory, which does not perform such an initialization task for scripts.
