1) The programming file formats generated by the Quartus
II software that support these two features are the
Programmer Object File(.pof) that is used with the
Quartus II programmer, and the Jam File(.jam) and Jam
Byte-Code File(.jbc) that are used with either the
Quartus II programmer or other programming tools.

2) Ensure that you enable this feature before programming
a MAX II device through the Quartus II programmer.
You can enable the real-time ISP feature by selecting
the Enable real-time ISP to allow background
programming(for MAX II devices) option from the
Quartus II programmer window. Refer Fig.2.

- To configure or program one or more devices with the
ByteBlasterMV cable and the Quartus II programmer.
1) Compile a project. The Quartus II compiler generates a
.sof file to configure APEX II, APEX 20K, Mercury, and
Excalibur devices. To program an EPC configuration
device, a .pof or JAM STAPL format file should be
used.

select which SOFs to include in the device chain. In
JTAG mode, you add specific devices and
configuration devices to the device chain, in addition
to POFs and SOFs, and you have several
programming options for each configuration device in
the chain. In JTAG mode, you can verify an EPC
configuration device’s contents against its
programming file data, check that a device is blank,
examine a programmed device and save its data to
file, or use its data to program or verify another
configuration device.
