3.6 Circuit and DAEObject Manipulation 277
(see also CircuitEquations in Section 3.5.1). The default setting is DesignPoint −> Automatic,
which means to use the design point given in the DAEObject.
Tolerance
Tolerance −> tol specifies the maximum relative deviation of the values of the symbols in a matching
group from the group’s mean value.
Please note that the option Tolerance is neglected if the DAEObject contains no design-point
information.
Examples
Load Analog Insydes.
