Configuration & Testing 1An encryption configuration file is the same size as a non-encryption configuration file. When using a serial configuration
scheme such as passive serial (PS) or active serial (AS),
configuration time is the same whether or not the design
security feature is enabled. If the fast passive parallel (FPP)
scheme us used with the design security or decompression
feature, a 4× DCLK is required. This results in a slower
configuration time when compared to the configuration time of
an FPGA that has neither the design security, nor
decompression feature enabled. For more information about
this feature, refer to AN 341: Using the Design Security Feature in
Stratix II Devices. Contact your local Altera sales representative
to request this document.
Device Configuration Data Decompression
Stratix II FPGAs support decompression of configuration data, which saves configuration memory space and time. This feature allows you to store compressed configuration data in configuration devices or other memory, and transmit this compressed bit stream to Stratix II FPGAs. During configuration, the Stratix II FPGA decompresses the bit stream in real time and programs its SRAM cells.
Stratix II FPGAs support decompression in the FPP (when using a MAX II device/microprocessor and flash memory), AS and PS configuration schemes. Decompression is not supported in the PPA configuration scheme nor in JTAG-based configuration.
Remote System Upgrades
Shortened design cycles, evolving standards, and system deployments in remote locations are difficult challenges faced by modern system designers. Stratix II devices can help effectively deal with these challenges with their inherent re-programmability and dedicated circuitry to perform remote system updates. Remote system updates help deliver feature enhancements and bug fixes without costly recalls, reduce time to market, and extend product life.
Stratix II FPGAs feature dedicated remote system upgrade circuitry to facilitate remote system updates. Soft logic (Nios® processor or user logic) implemented in the Stratix II device can download a new configuration image from a remote location, store it in configuration memory, and direct the dedicated remote system upgrade circuitry to initiate a reconfiguration cycle. The dedicated circuitry performs error detection during and after the configuration process, recovers from any error condition by reverting back to a safe configuration image, and provides

Characteristics
Operating Conditions Stratix®II devices are offered in both commercial and industrial grades. Industrial devices are offered in -4 speed grades and commercial devices are offered in -3 (fastest), -4, -5 speed grades.
Tables5–1 through 5–32 provide information about absolute maximum ratings, recommended operating conditions, DC electrical characteristics, and other specifications for Stratix II devices.
Absolute Maximum Ratings
Table5–1 contains the absolute maximum ratings for the Stratix II device family.

(1)See the Operating Requirements for Altera Devices Data Sheet.
(2)Conditions beyond those listed in Table5–1 may cause permanent damage to a device. Additionally, device
operation at the absolute maximum ratings for extended periods of time may have adverse affects on the device.
(3)Supply voltage specifications apply to voltage readings taken at the device pins, not at the power supply.
(4)During transitions, the inputs may overshoot to the voltage shown in Table5–2 based upon the input duty cycle.
The DC case is equivalent to 100% duty cycle. During transitions, the inputs may undershoot to –2.0 V for input currents less than 100mA and periods shorter than 20ns.
