In our design some RAM blocks are being inferred from our VHDL (no altera IP is being used).When targeting the device 10M16SCU169A7G and trying to compile the following error occurs: Error (16021): You specified a configuration mode that includes memory initialization, however memory initialization is not supported by the selected device. In the Device and Pin Options dialog box, choose a configuration mode without memory initialization. After following the intructions and selecting "Single Image", we run into the next error in the assembler: Error (14703): Invalid internal configuration mode for design with memory initialization Doing some research points out to the issues with MAX 10 SC boards and memory initialization issues: https://www.alteraforum.com/forum/showthread.php?t=56869 I though this was only with ROM blocks, Is it possible the inferred RAM blocks also trigger the same issue?, or perhaps I am missing a setting? If this is in fact the issue, then is there any known workaround? Thanks!
Hi,1. Can you provide your design so that we can replicate the issue? 2. Which Quartus Edition & Version are you using? 3. Please check with below link, https://www.altera.com/support/support-resources/knowledge-base/component/2017/error--14703---invalid-internal-configuration-mode-for-design-wi.html Let me know if this has helped resolve the issue you are facing or if you need any further assistance.

I will continue on this topic:
Why Quartus reports an Error (14703) and does not show the problematic file/line? I am using the same code on xilinx and intel FPGAs, and i am always having problem with this initialization with Quartus. I comment out all the ram initialization lines i found in my project ( signal mem : memory_type :=(others => (others => '0')); to signal mem : memory_type;) but i am still getting this error with no additional information and i cannot find another instance of initialized memory in my code.
So again: Why Quartus reports an Error (14703) and does not show the problematic file/line?
