Implementing ROM - which FPGA to use?

Hi all, I need to implement 5 look-up tables (for 5 DACs), with a total of ~800Kbits. I built a simple rom (didn't use a mega-function) - an entity with address and data pins and an internal ar...

KAZ has answered the question clearly. The maximum configuration image size for each FPGA type is written in the device hardware manual. I guess, you intend to use serial flash (Altera EPCS or compatible), but you didn't explicitely tell. 16 MBit is good upto EP3C55, see table 9-3, configuration file size. Additional memory space may be required for designs involving soft processors.
