Hi, I am trying to run OpenROAD-flow-scripts in a native Ubuntu 22.04, but am continuously encountering the following error, any idea how to fix this? I have downloaded yosys and klayout as well as openroad and all of them are building and working fine. But when I try to make the flow script Makefile, I am encountering this particular error. I tried to change paths for yosys, but its still persistent.

@Akshit Bhatia Looks like

yosys

isn’t installed. Can you try

which yosys

?

You should make sure it's installed and environment variables are set. Also, make sure you are correctly pointing to the yosys binary inside ORFS Makefile (look for `YOSYS`_CMD) as David mentioned.

I tried which yosys and its there, the path it shows for yosys is "/usr/bin/yosys", is that the issue?

There's a variable called YOSYS_EXE in flow/Makefile that should be pointing to the path you got from

which

the path I get from which yosys is "/usr/bin/yosys" and in the make file the path is "export OPENROAD_EXE=$(command -v openroad) export YOSYS_EXE=$(command -v yosys)" and when I run "command -v yosys" in the terminal I get "/usr/bin/yosys". Thats why I am not able to understand why I am getting this error again and again
