11.6.4.1. Tuning ATB Thresholds

If your design uses floating-point components, the autogenerated testbench uses a special floating-point comparison when detecting mismatches. Two thresholds influence the sensitivity of the mismatch detection:

  • Floating-point mismatch tolerance, which is the largest relative error that is not flagged as a mismatch
  • Floating-point mismatch zero tolerance, which is the largest magnitude for a signal value to be considered as equivalent to zero.

Procedure

  1. Click DSP Builder > Verify Design > Advanced.
  2. Enter new values in Floating-point testbench settings.
