System-level simulation techniques

Definition

System-level simulation techniques refer to methods used to model and analyze complex systems as a whole, rather than focusing on individual components. These techniques help in predicting the behavior and performance of integrated circuits and systems, particularly in the context of Terahertz engineering where multi-physical interactions occur. By simulating entire systems, designers can identify potential issues early in the design process, optimize performance, and reduce development costs.
