Hello Guys, so I added my own design (a single bit comparator) but it only contains config.tcl and not skywater_...._.config.tcl file. How can I generate one for my design since the specifications seem to be different for every design. also when i try to run it using flow.tcl it gives an error [TCL: yosys -import] Command name collision: found pre-existing command `cd' -> skip. [TCL: yosys -import] Command name collision: found pre-existing command `eval' -> skip. [TCL: yosys -import] Command name collision: found pre-existing command `exec' -> skip. [TCL: yosys -import] Command name collision: found pre-existing command `read' -> skip. [TCL: yosys -import] Command name collision: found pre-existing command `trace' -> skip. 1.

@ibad1112 Here, it says that that you are using a module
comp
that doesn't exist in the list of verilog files that you passed to Yosys. So that's the issue. Check ::env(VERILOG_FILES) and the includes inside your source code
