Signal threshold


Specifies the deadband region used during the detection of zero crossings. Signals falling within this region are defined as having crossed through zero.

The signal threshold is a real number, greater than or equal to zero.

Category: Solver


Default: auto

  • By default, the zero-crossing signal threshold is determined automatically by the adaptive algorithm.

  • You can also specify a value for the signal threshold. The value must be a real number equal to or greater than zero.


  • Entering too small of a value for the Signal Threshold parameter will result in long simulation run times.

  • Entering a large Signal Threshold value may improve the simulation speed (especially in systems having extensive chattering). However, making the value too large may reduce the simulation accuracy.
