Eldo Control Language
Advanced Simulation Options
Then, if many simulations use the same netlist file, at the end of the simulation the .chi file is the
.chi file of the last simulation.
Backup cir File
By default, the Control Language makes a copy of the netlist simulated inside tasks to provide a
trace in case debug is needed. To change this behavior, set the following option:
wdb File
.option backup_eldo_cl_netlists=0
By default, when waveform results are assigned to task local variables to be able to perform
some post-processing after a simulation, the waveforms are copied from the .wdb file generated
during the simulation to the main .wdb file. If many simulations are run and many waveform
results are used, the main .wdb can become very large and slow further simulations. To avoid
this problem, set the following option:
.option keep_eldo_cl_temp_waves=0
Then, waveforms results will be automatically deleted from the main .wdb file when they are
not used anymore (the waveform is deleted when all variables depending on this waveform
become out of scope). See functions operating on wdb files in “Library of Functions for Tasks”
on page 854 to know how to explicitly save waveforms in a .wdb file in this case.
Arguments
By default, arguments passed to Eldo on the command line will also be passed to Eldo processes
performing the Control Language simulations. If arguments are set with the args argument of
the simulation function, these new arguments will be appended to those passed to the main Eldo
process. For example, if you run Eldo with the arguments -compat or -premier, Eldo processes
performing the simulation will also be run using these arguments. To deactivate this behavior,
set the following option:
.option propagate_eldo_cl_main_args=0
Then, arguments set to the args parameter of the simulation function will be the only ones
passed to the Eldo processes performing the simulations.
