Use this to set the allowable device tolerance for components.

These device tolerances are used when running a Monte Carlo Simulation.

How To Set A Component’s Tolerance

Select the component(s) that you wish to change. If all resistors or capacitors are to be set the same tolerance, use the Select All Resistors or Select All Capacitors options from the Monte Carlo sub-menu on the Simulation menu.

Now use the Set Tolerance option from the Monte Carlo sub-menu on the Simulation menu.

The following dialog will be displayed:

Enter the tolerance in the edit box. You may use the ’%’ symbol here if you wish, so 5% and 0.05 have the same effect.

If the value is set to then some of the components you are changing have different tolerances. Clear this text and enter the required tolerance.

Which Component Types?

The type of the component is defined in its Part using the Edit Spice Dialog.

Device tolerances can be applied to the following component types:

Capacitors

Resistors

Inductors

Fixed voltage sources

Fixed current sources

Voltage controlled voltage sources

Voltage controlled current sources

Current controlled voltage sources

Current controlled current sources

Lossless transmission lines (applied to Z0 parameter)
