DC & Switching Characteristics
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.
Final timing numbers are based on actual device operation and testing.
These numbers reflect the actual performance of the device under
worst-case voltage and junction temperature conditions.

Performance
Table 6–35 shows Stratix GX device performance for some common
designs. All performance values were obtained with Quartus II software
compilation of LPM, or MegaCore® functions for the FIR and FFT
designs.
