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


The signal threshold is determined automatically by the adaptive algorithm.


Use the specified 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.


This parameter is enabled if the zero-crossing Algorithm is set to Adaptive.
