Configuration & Testing
The Quartus II software has an Auto Usercode feature where you can
choose to use the checksum value of a programming file as the JTAG user
code. If selected, the checksum is automatically loaded to the USERCODE
register. Turn on the Auto Usercode option by clicking Device & Pin
Options, then General, in the Settings dialog box (Assignments menu).

(2) The IDCODE's least significant bit (LSB) is always 1.
1 Stratix, Stratix II, Cyclone, and Cyclone II devices must be
within the first 17 devices in a JTAG chain. All of these devices
have the same JTAG controller. If any of the Stratix, Stratix II,
Cyclone, and Cyclone II devices are in the 18th or after they fail
configuration. This does not affect SignalTap II.
