#1629 Set default value for global_verbose_level Issue created by hakan-demirli Description If you follow the Interactive mode documentation and run any command, a blocking warning/error pops up.

can't read "global_verbose_level": no such variable

. Steps to produce: • Install OpenLane •

make mount

•

./flow.tcl -design inverter -interactive

•

run_synthesis

Solution is to run

set_verbose 1

command to set the mentioned variable. There is only one mention of this variable in #1525 but the main problem of that user was different and no one mentioned set_verbose. Proposal The variable global_verbose_level should have a default value. Maybe also a warning at the beginning of the interactive flow about the default verbosity level. But, the existing logs are enough in my opinion. The-OpenROAD-Project/OpenLane
