13.1 Analysis Types for Simulation
The simulation model can be analyzed in three different domains:
• Time domain (transient analysis or TR simulation)
• Frequency domain (harmonic analysis or AC simulation)
• Quiescent domain (DC operating point analysis or DC simulation)
• (used to determine the operation point for models with nonlinear components).
To select a simulator, click an option from the drop-down menu on the simulation toolbar. See
also “Starting the Simulator” on page 206.
Until it is changed, the last simulator selected (DC, AC, or TR) is used for future simulations.
To avoid calculation errors, please check the selected simulator before calculating a new simulation
model.
13.1.1 Transient Simulation
The TR Simulator is used to calculate the simulation model in the time domain. In the Schematic,
choose SIMULATION>PARAMETER and click the «TR» tab to set the parameters for the
TR simulator.
Components for Transient Simulation
Components for transient simulation:
• All internal components
• All VHDL-AMS components
• C models with definition for transient simulation
• Macros using appropriate models (internal components, C models, VHDL-AMS models)
Parameters of Transient Simulator
Simulation parameters control the simulation process. The choice of them are important for
an successful simulation. There are general and circuit simulator parameters. The values during
a simulation provide valuable information about the quality of a simulation result.
Simulation parameters can be used in equations and expressions.
General Simulation Parameters
THETA (23) Global ambient temperature for temperature dependent components
[°C].
TEND (40m) Simulation end time in seconds.
HMIN (10µ) Minimum time step in seconds.
HMAX (1m) Maximum time step in seconds.
