SOPC 5.0 Compile error?

Hello,

I get a very strange message during SOPC compilation that occurs during the

generation of the CPU:

The message is :

ERROR: In object ' ' of class e_dpram: can't access 'read_during_write_mode_mixed_ports' field

known fields are:

_AUTOLOAD_ACCEPT_ALL

_module_name

_already_declared_file...... this goes on for awhile.

I double checked my system, which is a standard C20 build with an added DMA.

I am using SOPC 5.0 to target and Altera Cyclone C20 dev board.

Any tips appreciated.

Thanks,

-Ray

    Try closing and opening SOPC Builder. Also, if your cpu was generated with a previous version, you could try deleting and re-adding it in 5.0.

    Sounds like you are suffering from version-itis.

    You are using a Nios II 5.0 with an older version of SOPC Builder (which comes bundled with Quartus).

    Contact your Altera representative and ask for the latest version of Quartus 5.0.

    Hello,

    Thanks for your inputs.

    I had tried reopening projecgt several times, problem persists.

    Also, I am using with Nios II 5.0, Quartus 5(beta) SOPC Builder 5 build 91.

    Still puzzled?

    Your Quartus 5.0 build 91 is too old.

    You'll need to get a more recent version.

    Thanks for tip James.

    I went and picked up build 134, supposed to be latest and see a new type of problem. Whereas before, I would see the cryptic error, now with build 134, the compile seems to get stuck during the arbitration build phase.

    I sent the earlier problem to Altera support and they have an SR bug on it.

    Thanks,

    I would like to know that as well, can you download a beta build somewhere?

    Hello,

    I do not believe that 5.0 has been released for general consumption yet. I got a 5.0 beta because I needed to compile for a new Cyclone II board that my company is working on.

    What I am really trying to do now is test the speed of DMA accesses with 5.0, but I get first the strange error with build 91 and then the stall with SOPC build 134.

    I might start a new thread to discuss this.

    Hi Ray,

    Ok, understood ;-)

    Well we are much closer to being done with 5.0 -- I suggest that if you haven't already done so, obtain a more recent copy and that should clear things up.. these sorts of things are not uncommon in early pre-release builds and (should) get caught by the QA process. There was a problem of arbitration generation taking a while, depending on the system, that could take system generation take quite a long time (but not stuck forever as you describe) -- this was recently addressed.
