1.2. Constraining Designs with Tcl Scripts

You can perform all your design assignments using .sdc and .qsf setting files. To integrate these files in compilation and optimization flows, use Tcl scripts. Even though .sdc and .qsf files are written in Tcl syntax, they are not executable by themselves.

When you use Intel® Quartus® Prime Tcl packages, your scripts can open projects, make the assignments, compile the design, and compare compilation results against known goals and benchmarks. Furthermore, such a script can automate the iterative design process by modifying constraints and recompiling the design.
