The Memory Editor allows you to enter, edit, and view the memory contents for a memory block implemented in an Altera device in a Memory Initialization File (.mif) or Hexadecimal (Intel-Format) File (.hex). You can create a new Memory Initialization File or Hexadecimal (Intel-Format) File, and then specify the memory contents for a memory block in the design. You can edit and adjust the memory cells and their values within the Memory Editor by filling a selected cell or cells with binary, hexadecimal, octal, or decimal values, editing individual cells, or custom filling an address range with a sequence of incrementing or decrementing values from a starting point.
