MAX 7000B device timing can be analyzed with the Altera software, with
a variety of popular industry-standard EDA simulators and timing
analyzers, or with the timing model shown in
devices have predictable internal delays that enable the designer to
determine the worst-case timing of any design. The Altera software
provides timing simulation, point-to-point delay prediction, and detailed
timing analysis for device-wide performance evaluation.
The timing characteristics of any signal path can be derived from the
timing model and parameters of a particular device. External timing
parameters, which represent pin-to-pin timing delays, can be calculated
as the sum of internal parameters.
between internal and external delay parameters.
