Eldo Netlist Setup
Simulator Commands and Options
• Display commands to control the messages and outputs generated from simulation.
• Simulation control commands to modify general options for simulation.
• Circuit description commands to describe the attributes of the circuit.
Simulator control options, specified with the .OPTION command, to modify execution
behavior; netlist options are divided into the following groups:
Simulator compatibility
Simulation speed, accuracy, and efficiency
Model control
Noise analysis
Simulation output control
Eldo Control Language
Optimizer output control
Netlist parser control
Miscellaneous simulation control
RC reduction
Simulation display control
File generation
Mathematical algorithm
Mixed-mode
Multiple .OPTION commands can be used in a netlist. A single .OPTION statement can
contain multiple options. The order of definition is not usually important. In case of a
double definition, the last specified value is used.
• Output commands define which simulation results will be written to the output files for
display, and include:
o
o
.EXTRACT
Extracts waveform information using a combination of arithmetic expressions or
pre-defined functions (.MEAS is also supported as an alternative).
.PLOT
Specifies which simulation results have to be kept by the simulator for graphical
viewing and post-processing. Results are written to .wdb binary output files for postprocessing.
