Error (16021) using 10M08SCE144C8G

I'm utilizing the MAX10 FPGA, specifically the 10M08SCE144C8G model, to generate sweeping sinewave signals using lookup tables and multipliers. However, during compilation, I encountered the followin...

Hi,
I checked which errors are raised in which situation.

You get error 16021 if you try to compile 10MxxSC with memory initialization configuration.
Compiling a design with initialized RAM but without respective configuration gives error 16031.

If you continuously get error 16021, you didn't manage to change the configuration. You can check project .qsf, it should e.g. contain an assignment
set_global_assignment -name INTERNAL_FLASH_UPDATE_MODE "SINGLE COMP IMAGE"

Your problem might be caused by a strange behaviour of the Device and Pin Options dialog. The displayed Configuration Mode does not necessary reflect the actual setting because it only shows legal values for the selected device. You need to change it to a different option and back to the intended setting to change the internal value.

I stated above that SC type can't implement lookup tables. That's not fully correct, it can't implement lookup table defined as initialized block ram (altsyncram IP). It compiles however inferred ROM without problems, except for a possibly large lcell utilisation.
