Checking Design Timing
To ensure that your design works, check the timing report to ensure that there is no
timing violation. It is important that the internal and I/O timings are met. The f
from the timing report indicates the maximum frequency at which your design can
operate. To ensure that the Cyclone III device interfaces correctly with other devices
on the board, check the t
when the Cyclone III device receives data from another device, make sure that the t
and t
register. Violating t
Metastable output can become incorrect for short durations, thus affecting the design
functionality.
When the Cyclone III device transmits registered data to another device, check the t
of the Cyclone III device to estimate the data arrival time for the external device.
For more information about the TimeQuest Timing Analyzer and the Classic Timing
Analyzer, refer to the
Timing Analyzer
