MaxLoader User’s Guide

(Programmer Object File) is a binary file generated by Altera assembler (Quartus and MAX+PLUS II). This file should be loaded for Altera MAX or EPC family devices only.

ƒBinary Format

Binary format does not specify the address or checksum of the file. The file contains the actual binary data. An example of this format is a DOS executable file with an .EXE or .COM extension. Binary format is generated for programmable memory devices. It is recommended to save your EPROM data as binary format in order to load the file as a standard file format later.
