The 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 a
timing budget estimation 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.
