AI Technical Summary

Technical Problem

The reliability of simulation model results in existing technologies is insufficient, resulting in limited trust in simulation results during system verification and making it difficult to effectively apply them to the early development stages of embedded systems.

Method used

By comparing simulated time series with measured time series, the accuracy of the simulation model is verified using error metrics such as mean squared error (MSE) and probability boxes (p-boxes). Statistical methods are combined to identify outliers and calibrate the simulation model parameters to improve reliability.

Benefits of technology

It improves the reliability of simulation models and the functional reliability of embedded systems, reduces statistical uncertainty in verification, effectively identifies and eliminates outliers, and enhances the trustworthiness of simulation results.

Abstract

A method (10) for a simulation technology system is characterized by the following features: obtaining (11) a time series by means of a simulation model of the system, wherein a value of energy change is assigned to at least one cognitive parameter of the simulation model; obtaining (12) at least one measurement sequence by means of corresponding measurements of the system; calculating (13) a real-valued error measure (15) of the time series obtained for that value relative to the measurement sequence and a distribution function (16) of the error measure (15) for each value of the cognitive parameter; and using (14) the following value for the simulation, wherein the distance between the distribution function (16) and the Haweside function is minimized.
