Honored ContributorThe Cyclone II EP2C35 has 105 M4K OnChip memory blocks. Each M4K has 4096 bits + 512 parity bits. Speaking of bytes, each M4K block has 512bytes (no parity), so if you use more than the available memory blocks, your design requires more than 105 x 512 bytes.
so you have 3 options. 1. use a bigger fpga if possible 2. reduce the memory usage 3. check the quartus settings, maybe some memory blocks can be swaped to registers.
