SIMPLORER 6.0 — Manual 531
All units used from simulator immanent components are derived from the SI Units system.
Quantity Unit Name Symbol
Length Meters m
Mass Kilograms kg
Time Seconds s
Electrical current intensity Amperes A
Temperature Kelvins K
Voltage (derived SI unit) Volts V
Qualifier of Parameters
Components are characterized by different physical quantities. A resistor, for example, is represented
by current and voltage in the simulation. System variables may be accessed by reading
(to use the actual quantity in expressions or to create an output) or writing (influencing
quantities). Use the following syntax to obtain access:
Name.Qualifier
Computations and outputs require access to system variables. The form and number of the
qualifier depend on the corresponding component.
All qualifiers are case sensitive and must use capital letters (that is R.V not R.v).
Predefined Variables
The simulator uses predefined variables for internal computation. If these variables are used
in a model description, an error message or unexpected effects result. All predefined variables
are case insensitive. See also “Using Simulation Parameters” on page 53.
Predefined variables cannot be used for names in a model description.
