Multi-processor aoc compilation

Altera_Forum · ‎03-09-2016

I am currently compiling a rather hardware-intensive kernel. The compilation time just got over 24 hours and it is still running.

I know Quartus can use multiple processors when compiling, but when I look at the Windows task manager, I only see one processor with one core active.

Can I use multi-processor compilation only from Quartus' gui or is there a way to let it use multiple cores?

(I have Quartus set to use all available processors.)

I have read something about this here:http://www.alteraforum.com/forum/showthread.php?t=478&highlight=multithread,

but that did not help.

I just saw Quartus map using 2 threads (for one minute it were even 5), so it seems to be working fine. I did not change my settings, only compiling a different kernel.

Some extra info: I just looked at the Quartus project settings, there the limit was set to 4 processors, but I have seen it use more than 4. So it looks like the command line Quartus does not use this.

hi,

you can try to open file: quartus_sh_compile.log or top.sta.rpt

and search "processor" or "Processor".

you will get something like this:

+------------------------------------------+
