File Support
The Quartus and MAX+PLUS II development systems provide
programming support for Altera configuration devices. The Quartus and
MAX+PLUS II software automatically generates a POF to program each
configuration device in a project. In a multi-device project, the software
can combine the programming files for multiple ACEX, APEX, FLEX, or
Mercury devices into one or more configuration devices. The software
allows you to select the appropriate configuration device to most
efficiently store the data for each ACEX, APEX, FLEX, and Mercury
device. Moreover, when compiling for ACEX 1K, FLEX 10KA,
FLEX 10KE, or Mercury devices, the MAX+PLUS II software
automatically defaults to generate the EPC1 or EPC1441 POF with the
programming bit set for 3.3-V operation.
All Altera configuration devices are programmable using Altera
programming hardware in conjunction with the Quartus or
MAX+PLUS II software. In addition, many manufacturers offer
programming hardware that supports other Altera configuration devices.
