Use the correct hardware setup when interfacing the Cyclone III device with 3.3/3.0/2.5-V
LVTTL/LVCMOS I/O systems.
Use the Quartus II software to check the restriction on the pin placement.
Minimize the simultaneous switching noise effect on the board with the following methods:

Connect the device unused pins to the board according to the behavior of the pins.
Terminate the signals according to the I/O standard and signal travel direction.
Perform board-level IBIS or HSPICE simulation.
Minimize the noise on the power planes.
Consider the power-up requirement and I/O behavior of the Cyclone III device during power
up.
Add the correct series resistance to the appropriate configuration signals based on the
configuration scheme used.
Use repeater buffers for the configuration signals when cascading Cyclone III devices in
multi-device configuration.
Ensure that the
Pull the configuration pins high or low through resistors with the recommended values.
Ensure that the devices in a configuration chain are connected properly.
To prevent the signals to the configuration pins from overshooting to more than 4.1 V, use
series resistors and buffers according to the setup.
Do not leave the

For AP configuration, select the flash memory from the Intel P30 and P33 families that can
support 40-MHz clock.
Check the pin connection for other pins of the configuration device or flash memory.
Use the
Depending on the on-chip debugging method used, reserve additional resources such as
LE, memory and I/O, and route the JTAG pins out.
Consider the trade-off between schematics or HDL for your design entry based on your
design’s complexity.
Other than the Quartus II software, consider building your design with third-party EDA tools,
SOPC Builder, or IP cores.
If you are using HDL for design entry, use the recommended coding styles.
