MAX V devices timing can be analyzed with the Altera Quartus
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.
For more information, refer to
This section describes the performance, internal, external, and UFM timing
specifications. All specifications are representative of the worst-case supply voltage
and junction temperature conditions.
Timing models can have either preliminary or final status. The Quartus II software
issues an informational message during the design compilation if the timing models
are preliminary.
Preliminary status means the timing model is subject to change. Initially, timing
numbers are created using simulation results, process data, and other known
parameters. These tests are used to make the preliminary numbers as close to the
actual timing parameters as possible.
