SOPC System w/ Quartus II

Thanks for the replies!

I found out that the SOPC system generation was NOT successful. The last line of the *_log.txt says "error in processing. system not successfully generated.", although the last line in the System Generator window says "info: system generation was successful."

I found out that my custom component is the problem. If I creat a SOPC system only with NIOS and the two on-board memorys, everything works fine. Analyses & Synthesis work fine, the pin assignment work fine, full compilation works and also the programming works fine. The *_log.txt has 70 lines and ends with "success: system generation completed." (see attachment sopc_log.txt).

If I add the custom component to my design, the log-file has 6411 lines and ends with and fails with

eval failed on this ptf-string:
      $ptf = ['SYSTEM SOPC' ,[
   'System_Wizard_Version = "9.00"',
   'System_Wizard_Build = "235"',
   
   'Builder_Application = "sopc_builder_ca"',
   ...

The entire error message is in the attachment sopc_log.w_component.txt.

I created the component using the SOPC Component editor. It has three avalon interfaces: one clock-sing, one mm-slave and one conduit. The TLC- and PTF-file are also in the attachment

Can anybody help me out and tell me what I did wrong?

You can certainly set the SoPC system to be your top level if you really want to. There are a host of reasons why not to do this but hey it's all up to you.

So you would also recomment to write a instance of the SOPC system and make this my top level design entity? Are there other possibilities, and what is the "usual" way to use an SOPC system in Quartus II?

I could not find any documents that discribe the interaction between Quartus and SOPC Builder (I already took a look at the Quartus II Handbook, Volume 4)
