Comparison of modeling approaches through hierarchical behavioral modeling of a GNSS receiver front-end

This paper analyzes and compares the mixed-signal modeling approaches (conservative, timed data flow, and event-driven, as well as the baseband modeling approach) through the hierarchical behavioral modeling of a GNSS (Global Navigation Satellite System) receiver front-end. Based on the result of the comparison, one hierarchical modeling flow is finally derived comprising multi-modeling approaches with reduced manual modeling effort.
