Hi Folks, I am developping a bigger project on an Altera FPGA with Quartus II (Lite Edition). Once the FPGA becomes fuller and fuller, it has turned out that I get considerable differences in timing results depending on the fitter initial seed value. I now want to try a larger number of seed values automatically with a tcl script. That script should set a seed value, run the fitter, then run the timing analysis and finally print out the worst case slack. Then it should increment the seed value by one and restart form beginning until a certain seed value is reached. My problem: I have no idea about how tcl works. So I do not even know where to start. Does anybody have a sample script I could base my script on that would help me to get through the task of writing such a script? Or maybe someone has already wrote such a script and would share it here? Remark: From old Xilinx times I know that ISE had such a functionality build in. Even though I like Quartus much more than the old ISE, this is the first function I am really missing.
If you are not familiar with tcl, you can use a bash script or a makefile to call the quartus software:
PROJECT = top BLASTER_IDENT = "USB-Blaster(Altera)" map: quartus_map $(PROJECT) fit: quartus_fit $(PROJECT) asm: quartus_asm $(PROJECT) program: quartus_pgm -c $(BLASTER_IDENT) -m jtag -o "p;output_files/$(PROJECT).sof"
Of course you need to set then new parameter first:
set_global_assignment -name SEED <value>
No need to fiddle with tcl scripts if you don't want to. This is exactly what Design Space Explorer (that is part of every Quartus installation since ages) is meant for.

Ok thanks a lot for both answers! Didn't know about Design Space Explorer. That tool is exactly what I need! But good to know that scripting is also possible via batch files.
Hello everybody I make a project of a PACMAN game in Quartus, and I really need help because it's the first time I work on VHDL / FPGA my task is to import the fruits and to position them on the labyrinth please help me ------------------------------------------------- bonjour tout le monde Je fait un projet d'un jeu PACMAN en Quartus , et j'en ai vraiment besoin d'aide car c'est la 1ère fois que je travaille sur VHDL/FPGA ma tache est d'importer les fruits ainsi de les positionner sur labyrinthe s'il vous plait aidez-moi
