3.2.1.3. Synchronizer Chain Statistics Report in the Timing Analyzer

The timing analyzer provides an additional report for each synchronizer chain.

The Chain Summary tab matches the Synchronizer Summary information described in the Synchronizer Summary Report, while the Statistics tab adds more details. These details include whether the Method of Synchronizer Identification was User Specified (with the Forced if Asynchronous or Forced settings for the Synchronizer Identification setting), or Automatic (with the Auto setting). The Number of Synchronization Registers in Chain report provides information about the parameters that affect the MTBF calculation, including the Available Settling Time for the chain and the Data Toggle Rate Used in MTBF Calculation.

The following information is also included to help you locate the chain in your design:

  • Source Clock and Asynchronous Source node of the signal.
  • Synchronization Clock in the destination clock domain.
  • Node names of the Synchronization Registers in the chain.
