Temporary Files
Eldo Control Language
Advanced Simulation Options
To perform simulations, a number of temporary files have to be generated on-disk. By default,
when the name and log parameters of the simulation command are not set, these files are
generated in a temporary directory located in the Eldo outpath directory, named
“eldo_cl_simu_” with an automatically generated number appended, for example:
eldo_cl_simu_12345.
To ensure that these files are automatically removed after the simulation has ended, specify one
of the following options:
• .option remove_eldo_cl_temp_files=3
All temporary files are removed (even if the child simulation has failed, so this option
should only be used when confidence that the simulation will complete successfully is
high, otherwise it may be difficult to debug).
• .option remove_eldo_cl_temp_files=2
All temporary files are removed except for the log file (in this case, the log file is
generated outside the temporary directory and has the same name as the temporary
directory: eldo_cl_simu_xxxxx.log) and also backup files of the generated simulation
file.
• .option remove_eldo_cl_temp_files=1
This is the default; only files that are not useful for debugging are removed (typically the
ecl_cmd script file used to launch the child simulation).
• .option remove_eldo_cl_temp_files=0
No temporary files are removed.
These options have an effect only if the name and log parameters of the simulation command
are not set; otherwise:
chi File
• If the name parameter is set and the value of the remove_eldo_cl_temp_files option is
more than 2, it is automatically set to 1.
• If the log parameter is set and the value of the remove_eldo_cl_temp_files option is
equal to 3, it is automatically set to 2.
The name of the netlist file can be specified through the name parameter of the simulation
function. By default, if many simulations are performed (in the same task) and they use the
same netlist file, each .chi file will be appended to the previous one. To change this behavior, set
the following option:
.option set_eldo_cl_sim_chi_append=0
