Honored ContributorAre Multiple SOPCs Possible
I am working on a video mixing task and have a system.sopc that does the mising of multiple video inputs. I would like to build a test pattern generator outside this sopc as a second sopc and use it to mimic the input video streams. Is it possible to have multiple sopc in the same Quartus project? If so, what are the naming rules?

Altera_Forumhi guy!!!!!!
yes it possible!!!...... normally... you can add another sopc as a new component......... or add another cpu in you existing sopc...... cheers Franz Wagner...........- Altera_Forum
Thanks. I'll go try it. Now that I know it's possible I'll get it to work.

you should try Qsys, it will be easier for multiple systems in one project
i've used a single SOPC Builder system for building TPG > CVO then looped back into a CVI > ??? > CVO - Altera_Forum
hello mr thepancake!!!!!!!
what really is this QSYS? what does that do? i have a project with 2 cpus.....can i use this qsys?? thank you .... Franz Wagner - Altera_Forum
Qsys is "SOPC Builder on steroids" :) In Qsys you can build a hierarchical design so all your systems can be instantiated inside a bigger system. In Qsys systems and components are treated as the same thing. You need to have a Quartus II subscription to use Qsys and I would recommend taking a look at the Qsys tutorial to find out more (along with the Qsys documentation in the Quartus II handbook).

are you sure Qsys needs a license? its listed as supported in 11.0 Web Edition:

You are correct, both versions support Qsys. I must have been spacing out when that decision was made :D
- Altera_Forum--- Quote Start --- Is it possible to have multiple sopc in the same Quartus project? If so, what are the naming rules? --- Quote End --- It is possible - just create two SOPC's and make sure you use different names of the SOPC's components, e.g. SOPC#1: sopc1_cpu sopc1_jtag_uart sopc1_onchip_memory SOPC#2: sopc2_cpu sopc2_jtag_uart sopc2_onchip_memory ..pay special attention to the name of the onchip_memory as the name of the generated HEX-file (containing your NIOS app) that should reside in that onchip_memory should match. I just posted another thread involving multiple SOPCs: http://www.alteraforum.com/forum/showthread.php?p=119670#post119670

For the onchip memory in each system you can specify a unique name for the memory initialization file instead of relying on the automatically picked name.
