qsf file

Hi,  

i generate the qsf file from c# to text file and then i load it to quartos 13.0.  

1. i need to know if the location of the string commands must be at fixed places in the file or it could be any were in the file ? 

is there a legality at the location of those commands ? 

F.E : 

At file that i compiled i see at the qsf file first of all the "set_global_assignment" commands , then "set_location assingment" commands and then "set_instance_assignment" commands (File Attached at txt format) 

it should be at this order ? 

 

2.Are there global commands or fixed strings at the qsf file that doesn't change no matter what the designer choose ? 

 

Thanks for help. :)

Rather than generating a QSF directly, I recommend you generate a Tcl script, which will then create the QSF for you. A Tcl script has a lot of advantages, including that any syntax errors will be more easily discovered in the command line. You could also have a static Tcl script that creates the project and then sources the C# generated assignments. 

 

See http://www.altera.com/support/software/scripting/sof-qts-scripting.html 

 

As for your specific question, the QSF does not have any sections, so assignments can be put anywhere, except from *_FILE assignments which need to be ordered within themselves in the order you want the tool to read them

Hi, 

 

QSF Files mean "Quartus Setting File" and they are TCL (Tool Command Language) scripts :  

usualy, All lines begin with a command follow by arguments BUT you may have substitutions of command (enclosed by square brackets) and variable (character '$' and name of variable). 

A line that begins by a '#' is a comment BUT be careful about brackets even in comments (common newbie error). 

 

QSF are written in very simple TCL (no nested command, no procedures...) 

TCL is case sensitive ! 

 

1. I don't think there is an order but it could be. See Quartus scripting in www.altera.com 

 

2. there are a few commands that are ignored (backward compatibility, or simply useless commands) (Maybe I misunderstood your question) 

 

3. there is an order on the files read by Quartus software. See Quartus scripting in www.altera.com or in help (quite ugly to search)

i got your recommendation about Tcl script . i looked at the link that you sent me but i didnt find out how i can i write script that generate QSF file . 

 

can i run the TCl script via command prompt ? if yes , what is the command that operate TCl script ? 

 

i need to write a script that create the QSF file according to the user requirements (pin assignments , current strength , I/O standard , slew rate , etc...) 

and i need to send those requirements to the script from the C# GUI .

This tutorial uses Tcl scripts for synthesis and simulation; 

 

http://www.alterawiki.com/wiki/using_the_usb-blaster_as_an_sopc/qsys_avalon-mm_master_tutorial 

 

as do the other example zip files downloadable from here 

 

http://www.ovro.caltech.edu/~dwh/correlator/cobra_docs.html 

 

Take a look at them. 

 

The Tcl scripts create a Quartus project, which includes the .qpf file and the .qsf file. Using Tcl allows you to consider these files as "generated" and as such you can ignore them (much like a C programmer does not care about .o files, they're just an intermediate file). 

 

If you want a GUI to represent your Tcl settings, then you'll just have to write your C# to understand the Tcl file. 

 

Cheers, 

Dave
