Defining and Running Simulations
This task will generate the simulation files in different directories (simu1, simu2, simu3, and
simu4).
All these generated files are extremely useful to debug simulations. Once the debug phase has
been completed and the simulations behave as expected, it is possible to force Eldo to
automatically remove these generated files. Refer to the section “Temporary Files” in
“Simulation” on page 1114 for more information.

Collecting Simulation Results
Once a simulation has successfully completed, the following simulation data can be saved into
task local variables, from where it will be available for post-processing:
• Values of parameters.
• .EXTRACT and .MEAS results if they have been given a label (for example:
.EXTRACT tran label=thresh4 xthresh(v(2,0), 4)).
• Waveforms if they have been given a name (for example: .PLOT tran u20_tran=v(2,0)).
These data are managed as output arguments of the simulation command, and their values can
be obtained by requesting them using their names or labels prefixed with a “@” character.
Example
The following testbench, tb_rc, instantiates an RC circuit, plots the voltage across the capacitor
and also extracts the time value when this voltage reaches 4V. The task t_simu runs the
simulation of this circuit and prints the time value when the voltage across the capacitor reaches
4V, calculated using two different methods.
