Tcl script does not run during compilation

To run a script during before compilation, you have to add it to your .qsf like so:

set_global_assignment -name PRE_FLOW_SCRIPT_FILE quartus_sh:assign_pin.tcl

Note that when the script runs, it does not act like Quartus is open. So you need to open and close the project. For example, if I had a project named gocubs and I wanted to create a pre-flow script called assign_pin.tcl that made a pin assignment, it would look like:

project_open gocubs

set_location_assignment PIN_M4 -to blaa

project_close

The big benefit is that it's true Tcl interpreter(unlike the .qsf reader) so you can script about whatever you want.

Thanks!

I have already this line in my .qsf:

set_global_assignment -name PRE_FLOW_SCRIPT_FILE "quartus_sh:version_and_time.tcl".

Do I have to add those lines to my .qsf?

project_open <project_name>

set_global_assignment -name PRE_FLOW_SCRIPT_FILE "quartus_sh:version_and_time.tcl"

project_close

The "project_open...project_close" lines go in the .tcl script. When you press compile, you should see messages that it's running the pre-flow script. (If the script is just writing out an HDL file that has version and time, i.e. it's not doing anything to the project, then you don't need the project_open/project_close.
