Is config.json must for gf180mcuC? I have config.tcl for my design. Getting error as below: maltik@ip-172-31-41-118:~/uP16_gf180$ make soc_config make -C openlane soc_config make[1]: Entering directory '/home/maltik/uP16_gf180/openlane' make[1]: * *No rule to make target 'soc_config/config.json*', needed by 'soc_config'. Stop. make[1]: Leaving directory '/home/maltik/uP16_gf180/openlane' make: * [Makefile107 soc_config] Error 2 maltik@ip-172-31-41-118:~/uP16_gf180$ ls openlane/soc_config/ config.tcl

can you share your config.tcl?

I have converted config.tcl to config.json. Now I'm able to run the flow
