14.x Timing Analyzer - Does Timing Analyzer include the flight time delay?

Description

Does Timing Analyzer/TRACE include the flight time delay?

Solution

Beginning with 6.1i, the flight time delay is used by Timing Analyzer/TRACE when calculating the I/O timing. However, it is only used for flip-chip packages.

You can run the "speedprint" command to determine if your device and package have flight times included in the timing analysis.

If you run "speedprint 5vlx30", the following section provides information on which packages have flight time information for timing analysis.

The following list of packages have individual package flight times for each pin on the device:

  • ff672
  • ff896

The I/O Timing that is affected by the flight times is also provided with the "speedprint" command. All of the timing delay types that start with "Tio" are affected by the flight times. The timing delay types are separated into the corresponding components, such as DIFFS, IOB, and so on. The DIFFS and IOB components contain the timing delay types that are affected by the flight times. The flight time value is subtracted from the list of delay values from the speedprint command.

For example, if you enter "speedprint 2vp7" (v1.92), the following timing delay types for IOB are reported:
