MAX 3000A Programmable Logic Device Family Data Sheet
MAX 3000A device timing can be analyzed with the Altera software, with
Timing Model
a variety of popular industry–standard EDA simulators and timing
analyzers, or with the timing model shown in Figure 10. MAX 3000A
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.

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. Figure 11 shows the timing relationship
between internal and external delay parameters.
