9.9.2. Calibration Error or Quantization Error

Hardware devices use calibration algorithms when delay information is unknown or incomplete. If the delay information is unknown, the timing analysis of the calibrated paths has to work with incomplete data. This unknown information may cause the timing analysis calibration operations to pick topologies that are different than what would actually occur in hardware.

The differences between what can occur in hardware and what occurs in the timing analysis are quantified and included in the timing analysis of the calibrated paths as quantization error or calibration error.
