    Thanks for the response Sheng. Sorry, I couldn't provide the source due for proprietary reasons.

I had removed a design component that isn't required anymore to free up resources (it is in the SOPC table of connected components), but I could still find it in the quartus settings file. Apparently, it was defined as a design partition (possibly for incremental compile reasons?). I’m not the original designer, so I’m not aware of the design decisions that went into setting that up. I deleted it from design partition table, then I could compile successfully. Would have been nice if tool had indicated “invalid design partition” instead of “internal error”. Regards, Grady

Hi Grady,


I think the reason for that is old version Quartus is no more managed by design team. The latest Quartus don't have that problem as it will show partition hierarchy error instead of just internal error.


Btw, glad to hear that your issue has been resolved. I'll now transition this thread to community support. If you have a new question, feel free to open a new thread to get the support from Intel experts.


Thanks!
