� � «Output»
If the box is checked, the variable is saved in the result file (.sdb) during the simulation.
Please note: If you want to display a variable value, you have to select the box in the output
dialog or in a Display Element. If the box is deactivated, you cannot display the variable value
after the simulation. See also “Defining Displays and Outputs” on page 51.
DES Solver
>>Basics>Tools>Equations
The DES model integrates differential equation systems independent from electrical nodes
and without equivalent circuits for circuits and block diagrams. Order and dimension of the
equation system are unlimited. The component cannot be used with AC and DC simulation.
DES models are solved in a separate differential equation system. The simulation parameters
HMIN and HMAX from the TR simulator are valid for the DES model too. The DES model is calculated
after the circuit module. See also 13.6 “Simulator Backplane” on page 418.
Please note: If you use the Runge-Kutta algorithm, the matrix M with the highest order must
be non-singular.
