Network Configurations
In SIMPLORER only ammeters are allowed as controlling components for current controlled
elements. These must be inserted properly in the controlling branch. If sources are part of mutual
controlling sources in the circuit, stability problems may occur if the total gain of the loop
is greater than or equal to one.
The following types of network configurations are invalid:
• Series connection of ideal current sources
• Series connection of inductors and ideal current sources
• Series connection of inductors with different initial values of current, I01≠I02 • Series connection of an inductor with an initial current value and an opened ideal switch
or nonconducting system level semiconductor
• Parallel connection of ideal voltage sources
• Parallel connection of capacitors with ideal voltage sources
• Parallel connection of capacitors with different initial values of voltage, V01≠V02 • Meches which consist only of ideal sources (short-circuit)
• Open-ended branches

Action Description Syntax in Value
CALC The variable is calculated at each simulation step and
each transition from one state to another.
var1:=100*t
STEP The variable is calculated at each valid simulation step. var2:=2*t
CATI The variable is calculated outside the state graph and before
the calculation of the electric circuit.
var3:=sqrt(t)
SET The variable is calculated only once at the moment of acti- var4:=2.5
vation of the state.
