Arguments
| Parameter | Type | Description |
|---|
| pulseWidth | decimal | Specifies the threshold value for pulse width. The signal bounce pulse width must reach this
value before the signal bounce can be recognized for SSN Analysis.
Valid values are 0 ns or 1 ns. A value of 0ns means any signal
bounce with pulse width over 0 ns is recognized for SSN analysis. A
value of 1 ns means only signal bounces with pulse width at or above
1 ns are recognized for SSN analysis. |

Error Codes
| Error Code | Description |
|---|
| None | pulseWidth: Invalid argument value: 'value' (expecting integer value). |
| None | Parameter 'pulseWidth' must be a positive integer value. |
| None | Parameter 'pulseWidth' has illegal value. |
| None | Required parameter 'pulseWidth' is missing. |
| None | Parameter 'param_name' is not defined. Valid command formatting is 'set_pulse_width -pulseWidth "integer value"'. |
