Statistical Processing
Controlling a Monte Carlo simulation with ECL relies on the ECL extended simulation flow.
The Monte Carlo flow is dedicated to advanced users, with a strong knowledge of statistics.
This is not supported by Eldo Premier.
The flow to control a Monte Carlo simulation is as follows:
• Activate the extended simulation flow
The first function to call to activate the ECL Monte Carlo flow is the _simu_load
function to load the netlist in the extended simulation flow.
Tip
See also Simulation Dynamic Control.
• Activating the Monte Carlo Flow
The ECL Monte Carlo flow is activated using the function:
_simu_set_mc_flow([max_nb_runs])
• Accessing Statistical Parameters
After the netlist is loaded and the ECL Monte Carlo flow activated, you can access
statistical parameters, managed internally by ECL and identified by an index.
The first index is 1 and the number of statistical parameters is given by a call to the
following function:
_simu_get_nb_stat_params
Use the following functions to access data related to statistical parameters:
_simu_get_stat_param_name
_simu_get_stat_param_distrib
For uniform and normal distributions, you can call the following functions:
_simu_get_stat_param_nom
_simu_get_stat_param_ref_param
_simu_is_stat_param_dev
_simu_is_stat_param_locked
_simu_get_stat_param_dev
_simu_get_stat_param_nb_draw
_simu_is_stat_param_devx
Use the following functions to parse their names:
