PowerPlay Early Power Estimator and PowerPlay Power
Analyzer to estimate the device power.

Timing Model and Specifications
MAX V devices timing can be analyzed with the Altera Quartus
®
II software, a variety
of industry-standard EDA simulators and timing analyzers, or with the timing model
shown in
MAX V devices have predictable internal delays that allow you 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.

You can derive the timing characteristics of any signal path from the timing model
and parameters of a particular device. You can calculate external timing parameters,
which represent pin-to-pin timing delays, as the sum of the internal parameters.
