Parameters of AC Simulator
In the Schematic, choose SIMULATION>PARAMETERS and click the «AC» tab to set the parameters
for the AC simulator.
Voltage and current for AC analyses are defined for electrical sources and block sources in the
simulation model. In the «AC - Parameters» dialog of sources you can define either magnitude
and phase or real and imaginary part of the AC value. This value can be constant or dependent
on other quantities. In the View Tool and the Display Elements, wave forms are drawn
in the frequency domain. See also 12.2.1 “View Elements” on page 369.
General Simulation Parameters
THETA (23) Global ambient temperature for temperature dependent components
[°C].
FSTART (40m) Start frequency [Hz].
FSTOP (10µ) Stop frequency [Hz].
FSTEP (1m) Frequency step width (linear sweeptype) or points per decade (decadic
sweeptype).
ACSWEEPTYPE (1) Sweep type, 0=linear or 1=decadic.
Solver Parameters
EMAXAC (1u) Maximum error [A]
Selecting AC Simulator for Simulation
To start an AC simulation the AC simulator must be selected in the simulation toolbar. Open
the drop-down list and select «Simulator AC». If you start a simulation, the simulator selected
in the toolbar, is used. Please note, the simulator is used for all following simulations as long
as another simulator is selected.
13.1.3 DC Simulation
The DC Simulator is used to calculate to determine the operation point for simulation models
with nonlinear components in the quiescent domain. The voltage and current information
about the operating point is saved to the .sdb file of the simulation model automatically. The
voltage values for the computed operation point is automatically displayed on the sheet at the
components. The menu commands CONNECT>SHOW DC RESULTS and CONNECT>HIDE DC RE-
SULTS switches the labels at the components on and off. See also “Connect Toolbar and Menu”
on page 48.
Components for DC Simulation
Components for DC simulation in the «Basics» tab:
• Passive Components
• Electrical Sources (except for Fourier source)
• Switches (except for controlled switches)
• Semiconductor System Level
