DE0-Nano SoC Kit - Questions about Qsys and automatic tcl pin assignments

Hi, not sure if you've found your answers by now, but for the benefit of the others, here are some details:

I assume you are refer "hps_sdram_p0_pin_assignments.tcl" that needs to be run after the Qsys generation. Quartus should have a small window (in my case, above the message window) that says whether the tcl script is executed successfully.

However, if you use an existing design example that already has the HPS assignment done previously, running the script above will not change any pin assignments (obviously) as they have been defined before.
