Quartus II bug

I think I found a bug in Quartus II (version 9) or the software works that way.

So, I may be wrong, but here is the thing.

Every time I compile a project the software makes a new process (a window process), and it can be small or moderate or big (talking about memory size on window work station) - depending on project size.

So, if I compile the same project over and over again (let's say 20 times), then the Quartus makes so many processes (20 of them running at the same time), and if you are not aware of that and your system has limited memory, then you are in a big trouble - most likely a blue screen or the Quartus crashes.

Basically, I have to open a task manager and kill all those processes manually (except a newest one) - time consuming really

Anyone knows a solution for this phenomena ?

Thank you

    What's the process? (quartus is the gui, while each part of a compile is a separate one, like quartus_map, quartus_fit, etc.) I run a ton of projects on a laptop, and they close nicely each time. What you're seeing is by no means the norm. If no one else responds with the same issue(and a fix), you might want to open a Service Request on altera.com.

    "What's the process?"

    In a windows envirovment a process is either an application (exe file) run by a user or service (exe file too) but that is running in a background.

    So, what I am saying is this:

    quartus_sh.exe is running when you finish compiling a project, and that is not an issue. The issue is with a multiple quartus_sh.exe running at the same time (depending how many times the project is compiled).

    However, I can live with it. But, it is just enoying phenomena.

    It would be much better when a new instance is created (quartus_sh.exe) the old one should be killed.

    Thank you

    I didn't explain right, as I know what process, but quartus will launch multiple processes during a compile. Open the GUI and quartus.exe shows up. Hit compile, and quartus_map.exe shows up, then quartus_merge.exe, etc. Quartus_sh.exe is the shell, which means you're running from a script. Can you give more details how you're running your compiles, maybe attach your script, and that might show what's going on. When running a compile from command line, the simplest way, which I do all the time, is:

    quartus_sh --flow compile --64bit project_name -c revision_name

    (--64bit and -c revision_name are both optional, I'm just in the habit of adding them)

    Frankly I dont have the solution ... But I realized that this version of the actual program contains many bugs, so I preferred to work 7.2 version. Try it!
