TCL Scripting

[Altera_Forum]

I wrote different style of tcl scripts and has caused the error. 

 1st style: quartus_sh -t project_open.tcl quartus_sh -t pin_assignment.tcl  2nd style quartus_sh -t pin_assignment.tcl -project Test  project_open.tcl project_open Test  pin_assignment.tcl set_global_assignment .....  1st and 2nd style get an ERROR: Open project does not exist..  3rd style (Working) quartus_sh -t pin_assignment_new.tcl  pin_assignment_new.tcl project_open Test set_global_assignment .....  My question is does it necessary to include project_open <project_name> in tcl file when i want to call quartus_sh -t <>.tcl  Can i do it using 1st style or 2nd style? Or any better way?  Thanks

Look as far as i know the open project_open command should be present on the very first line of any assignment you are trying to make to the project. 

 Suppose in the first case when you are executing the first command it should not throw an error. The second tcl file however is an all new execution in the quartus shell it wont have any reference to the previous command executed. The second command seeks to make assignments but the project is not visible to it. So i guess the 3rd style is required.   Now coming to your second case after you give the name for tcl file you have to provide the script arguement i dont thing the -project option will work, it might not throw a syntax error for that but it wont have any effects.   GOOD LUCK

if that is the case then i have no choice to stick with the style. Thanks
