Figure 1–7 shows the timing diagram for the oe and dyn_term_ctrl signals.
Duty Cycle Distortion (DCD) Specifications
Table 1–51 lists the worst-case DCD for Stratix IV devices.
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.
f The Excel-based I/O Timing spreadsheet is downloadable from the Literature:
