doubt in nios

[Altera_Forum]

what are the file formats that EPCS device will support?

You can't create non-volatile ram inside a fpga. If you have small nios projects you can either store your programm in an epcs device which you need to configure your fpga or for bigger programms in an external flash ram.  

 I think it's more comfortable to use c-code than (v)hdl-code.

But for LCD the NIOS processor isn't necessary =] You can design hardware LCD controller.

actually, it is perfectly reasonable to have a ROM in the FPGA image, and run code from that directly. That way the FPGA config includes the program data. only the large memory blocks (MRAMs) can't be preloaded with data.

To store code in ROM in fpga image, nios is necessary or not?

What do you mean ? If you want to build NIOS system it's necessary to attach code to programming file if you want NIOS to run this code from internal FPGA memory.  

If you want to store code (just any code) for internal FPGA memory initialization, the NIOS processor isn't necessary.
