I/O Timing  
I/O Timing  
Altera offers two ways to determine I/O timing—the Excel-based I/O Timing and the  
Quartus II Timing Analyzer.  
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 you complete place-and-route.

You can download the Excel-based I/O Timing spreadsheet from the Arria V Devices  
Literature webpage.

Programmable Output Buffer Delay  
Table 2–47 lists the delay chain settings that control the rising and falling edge delays  
of the output buffer. The default delay is 0 ps.

Control assignment to either positive, negative, or both edges, with the specific values stated here (in ps) for the  
Output Buffer Delay assignment.
