Signal Integrity
Stratix III devices simplify the challenge of signal integrity through a number of chip,
package, and board level enhancements to enable efficient high-speed data transfer
into and out of the device. These enhancements include:
■ 8:1:1 user I/O/Gnd/V
CC
ratio to reduce the loop inductance in the package
■ Dedicated power supply for each I/O bank, limit of I/Os is 24 to 48 I/Os per bank,
to help limit simultaneous switching noise
■ Programmable slew-rate support with up to four settings to match desired I/O
standard, control noise, and overshoot
■ Programmable output-current drive strength support with up to six settings to
match desired I/O standard performance
■ Programmable output-delay support to control rise/fall times and adjust duty
cycle, compensate for skew, and reduce simultaneous switching outputs (SSO)
noise
■ Dynamic OCT with auto calibration support for series and parallel OCT and
differential OCT support for LVDS I/O standard on the left/right banks

Reference and Ordering Information
The following section describes Stratix III device software support and ordering
information.
Software Support
Stratix III devices are supported by the Altera Quartus II design software, version 6.1
and later, which provides a comprehensive environment for
system-on-a-programmable-chip (SOPC) design. The Quartus II software includes
HDL and schematic design entry, compilation and logic synthesis, full simulation and
advanced timing analysis, SignalTap
®
II logic analyzer, and device configuration.
f For more information about the Quartus II software features, refer to the Quartus II
Handbook.
The Quartus II software supports a variety of operating systems. The specific
operating system for the Quartus II software can be obtained from the Quartus II
Readme.txt file or the Operating System Support section of the Altera website. It also
supports seamless integration with industry-leading EDA tools through the
NativeLink
®
interface.
