Memory Initialization for the ALTUFM_I2C Megafunction
The MAX V UFM physical memory block contains a 16-bit wide and 512 deep (9-bit
address) array. The ALTUFM_I2C megafunction uses the following smaller array
sizes:

Altera recommends that you pad the .mif or .hex file for both address and data width
to fill the physical memory map for the UFM block and ensure the .mif or .hex file
represents a full 16-bit word size and a 9-bit address space.

of 1-Kbit memory size. The ALTUFM_I2C megafunction byte address location of 00h
to 3Fh is mapped to the UFM block address location of 000h to 03Fh. The
ALTUFM_I2C megafunction byte address location of 40h to 7Fh is mapped to the
UFM block address location of 1C0h to 1FFh. Altera recommends that you pad the
unused address locations of the UFM block with all 1s.
