Handbook.
Power Consumption
®
Designers can use the Altera PowerPlay Early Power Estimator and PowerPlay
Power Analyzer to estimate the device power.
f
For more information about these power analysis tools, refer to the Understanding and
Evaluating Power in MAX II Devices chapter in the MAX II Device Handbook and the
PowerPlay Power Analysis chapter in volume 3 of the Quartus II Handbook.
Timing Model and Specifications
®
MAX II devices timing can be analyzed with the Altera Quartus II software, a variety
of popular industry-standard EDA simulators and timing analyzers, or with the
timing model shown in Figure 5–2.
MAX II devices have predictable internal delays that enable the designer to determine
the worst-case timing of any design. The software provides timing simulation, point-
to-point delay prediction, and detailed timing analysis for device-wide performance
evaluation.
