SIMULATION SYSTEM AND METHOD THEREOF AND COMPUTING SYSTEM INCLUDING THE SIMULATION SYSTEM

摘要

In a simulation system and method thereof, the simulation includes, when a function value for a nominal point (NP) of an input is a first value, running a first simulation on the input; and when the function value for the NP of the input is a second value different from the first value, running a second simulation on the input. Here, the running of the second simulation may include (a) setting a boundary of an input distribution for the second value as a first distribution value, (b) generating input samples within the set boundary of the input distribution, (c) obtaining a worst case point (WCP) for the input by performing machine learning on the generated input samples, and (d) repeatedly performing the steps (a) to (c) while shifting the boundary of the input distribution until the boundary of the input distribution reaches a minimum critical value.

1. A simulation method using a computing system including one or more processors, the simulation method comprising:
when a function value for a nominal point (NP) of an input is a first value, running a first simulation on the input; and when the function value for the NP of the input is a second value different from the first value, running a second simulation on the input; wherein the running of the second simulation comprises: (a) setting a boundary of an input distribution for the second value as a first distribution value; (b) generating input samples within the set boundary of the input distribution; (c) obtaining a worst case point (WCP) for the input by performing machine learning on the generated input samples; and (d) repeatedly performing the steps (a) to (c) while shifting the boundary of the input distribution until the boundary of the input distribution reaches a minimum critical value.
