Altera: set pin locations using tcl

1, compile the project;

2, store current tcl settings: Project –> Generate Tcl File from Project…

3, modify the generated tcl file.

Add pin assignment in section like “# Make assignments”:

The format is: set_location_assignment PIN_xx –to <signal>

4, Turn it to a compile script.

Until now, the tcl file is still a project setting. We will turn it into a compile script by adding a command in front of “# Close project” block:

The command is: execute_flow –compile.

This command tells Quartus to carry out the compile. However, to make this command recognizable to Quartus, we need to import a new package at the top of the script:

The command is: package require ::quartus::flow.

5, Run script.

Run script in Tcl window: source xxx.tcl
