I/O Timing
Altera offers two ways to determine I/O timing:
■ Using the Microsoft Excel-based I/O Timing.
■ Using the Quartus II Timing Analyzer.
The Microsoft Excel-based I/O Timing provides pin timing performance for each
device density and speed grade. The data is typically used prior to designing the
FPGA to get an estimate of the timing budget as part of the link timing analysis. The
Quartus II timing analyzer provides a more accurate and precise I/O timing data
based on the specifics of the design after place-and-route is complete.
f The Microsoft Excel-based I/O Timing spreadsheet is downloadable from the
Literature: Arria II Devices web page.
