Locate a node in Design using command line

Hey all,

I am trying to write a script For Quartos to find a critical path of a design in Verilog code. I believe that we are provided till report timing commands of Timing Analyzer tool. There is a capability in GUI to right click on nodes reported in timing report, and select "Locate in -> the Desing file" ( or locate path -> in Tech map viewer) but i could find any command line way to do them. If there was any, i could pars timing file and traverse trough code lines in Verilog.

Does any body know about any commands ?!

Or does anybody have better idea to find critical path in Verilog code ?!
